Security Evals Have Become Memory Tests

Introduction

We gave various models files from SusVibes tasks with a vulnerable function removed, with no network access and no tool calls. Every OpenAI and Anthropic model we tested recognized the project behind 28-29 of 30 tasks, even after various attempts to obfuscate the code. Some Anthropic models went even further: when we asked them to implement a feature that we had removed, Claude Fable 5.2 reproduced 91% of the removed lines verbatim on average (even reproducing the comments), and Opus 5.5 88%. This behavior showed up even when we fed the model normal prompts, as Opus 5.5 would write near-copies of upstream code in 61% of tasks we gave it when prompts sounded like assigning tasks.

This blog post was originally supposed to be about us, SquidProxyLovers, releasing our own security eval. However, along the way, we discovered that many of the security evals out there (beyond just SusVibes, which has received criticism for various reasons [2] [3]) no longer test what they were initially meant to test. We claim that evals that are built using real code sources (even if they were transformed in a way that preserves semantic meaning, as evals like SecRepoBench did [4]) with real CVEs do not serve as a good benchmark of a model’s capability to write secure code, because strong models are increasingly capable of recognizing the original projects and reciting the original code, with no internet access. Much of the earlier criticism of these benchmarks was aimed at agents that were retrieving answers from the Internet or from git history, but we show this problem remains even when network access and tool calls are disabled, making such external retrieval impossible. To be clear, this isn’t just test-set contamination, since this involves the benchmark being included in the training data. Here, the benchmark never has to be leaked, since if the original project is in the training data, tasks built from it are no longer good metrics for evaluation. To show this, we rewrote security eval tasks from scratch with just a description of its behavior and verified it still functioned the same way as the original tasks and thus did not directly have any code overlap. Models were still able to recognize the original file and recite the fix to the original code’s vulnerability, with Opus 5.5 in some cases writing the same function verbatim. When this happens, the score a model receives is based on what version the model remembers: if it remembers an older version, its result is insecure, and recalling the fixed version leads to a secure version. Neither of these outcomes is representative of how the model would behave on unseen code, which weakens the eval’s utility. We also demonstrate that evals can still be meaningfully run on real code, but it requires significant transformations that lose semantic equivalence.

TL;DR

• Security evals that are built from real vulnerable code have become memory tests, even without tool calls and network analysis which previous criticisms have argued are the cause. Both closed-source frontier models and open-weight models recognize the open-source projects these tasks come from, sometimes well enough to recite the original code back verbatim.
• This confounds the scoring of security evals. Rather than testing a model’s ability to write secure code, it instead tests whether a model is able to recite old vulnerable code or new fixed code. Neither outcome shows how a model performs on code it has not seen before.
• This is not ordinary test-set contamination. Unlike test-set contamination, the benchmark itself does not have to be present in training data for models to memorize answers. Rather, the choice of popular open-source projects itself is the issue, since they are exceedingly present in training data. Furthermore, because of their ubiquity, transforms such as renaming, obfuscating, or even rewriting the code from scratch didn’t stop models from being able to recognize it.
• Although nearly all large models can recognize the original codebases that these security eval tasks are based on, Anthropic’s models seem to recite the missing code verbatim far more often than others. This fascinated us, as we rarely see such large objective differences between OpenAI and Anthropic models with identical prompts.
• Disguising real code is a losing race. Models are already able to reverse semantics-preserving transforms, and there’s no reason to expect tricks that work today to continue working.
• For now, we recommend security evals use real vulnerability patterns in code that isn’t copied from real projects, with both a public and private dataset to maintain some degree of transparency. In the longer run, private synthetic tasks built on vulnerabilities that have never before been reported are the most robust solution.

What do you mean by the models are memorizing code?

Consider this file, which is a task in SusVibes [1], a well-known security eval where the task is to see whether models write vulnerable code by deleting a function known to have a CVE and then tasking models with reimplementing it. This specific task originated from the codebase of Jinja, a popular engine to write templates with almost 12k stars on GitHub.

This specific file is an excerpt from filters.py, which is where all the built-in Jinja filters are contained. In 2024, two vulnerabilities were reported in one of them: xmlattr, which turns a Python dictionary into HTML attributes. Although attribute values were escaped, attribute keys were not, so malicious keys like onclick=alert(1) could inject their own attribute and run arbitrary JavaScript code (CVE-2024-22195 and CVE-2024-34064). In order to succeed, a model would have to independently implement the function while escaping attribute keys. However, we noticed that models, including open models such as GLM-5.3-prime, DeepSeek-V4.1-Flash, Kimi K3, Qwen 3.8 Max Prime, as well as closed-source OpenAI models and Anthropic models, immediately recognized that the code was from Jinja, even when given no network access and no tool calls.

Although this alone would call into question the utility of an eval (if a model can immediately recognize a codebase just from its weights, then the resulting implementation would be influenced by this knowledge, which is unrepresentative of how new code is written in the real world), we then noticed that the code that Anthropic models such as Opus 5.5 and Fable 5.2 produced was strikingly similar to the upstream code.

Let’s play a game: can you tell which of the two functions above was generated by Opus 5.5 and which is the original code from the repository? The only difference: Opus didn’t include two changelog lines from the comments, which were also the lines that documented the fixes to the two reported CVEs. Other than that, everything, even the wording of the comments, was completely identical. From memory, Opus and Fable copied the real code without tool calls or network access by remembering how Jinja fixed it, not by reasoning about how potential code could be vulnerable.

Even worse, the code they sometimes wrote for some of the other tasks was the old version that still contained CVEs, as shown in the example below with Babel, a Python internationalization library [7], where Opus recited from memory verbatim code (comments included) that contained a path traversal vulnerability that could result in ACE (CVE-2021-42771).

We originally suspected that surrounding code gave project names away, which led to this recitation. We tested this: as we show below, even heavily obfuscated versions of files are recognized by models, which means the true extent of this issue runs deeper.

Why should we care, what benchmarks are affected?

There’s one thing we need to be careful about, and it’s that none of the models did anything wrong. Technically, they are writing secure code some of the time when they recite memorized code (we hypothesize that reciting code is often more right than wrong in training, which is why this phenomenon arose). In the field of security, where the result is more important than how it got there, saying that the issue is with the model is counterproductive to the real goal of having models write secure code. The main issue is that although this style of security eval used to be good at evaluating the skill of a model’s ability to write secure code while also spending relatively little effort writing code with high-level vulnerabilities, models have evolved in capability to render it less useful than in the past. To make difficult security evals that push a model’s default capabilities to write secure code, the tasks must measure how well the model independently writes code rather than how well it memorizes updated versions of famous codebases.

Below is a non-exhaustive table of security evals we believe to be affected:

Notably, evals that use synthetic test cases cause models to react differently, which supports our claim that this is not just test-set contamination. For synthetic evals, the issue is mostly that they are publicly available, so models with later cutoff-knowledge dates may train on them and thus memorize them. Synthetic evals are solved with the usual fixes that fix test-set contamination, such as reducing textual overlap (renaming identifiers) and rewording prompts. With these fixes, Opus 5.5, the worst offender of reciting code, wrote code that matched only obvious lines, which held across multiple synthetic evals such as Juliet and SecurityEval [11]. However, this was not at all the case with real-CVE evals, which resisted almost everything we tried.

Additionally, even if a model doesn’t recite code verbatim, recognizing the codebase alone still weakens the utility of a security eval. GPT-6.1-sol rarely recites code, but it recognizes codebases just as well as Opus 5.5 and Fable 5.2 do, and this influences the code it writes. Given a version of Jinja’s filters.py that was obfuscated and rewritten from scratch, it still consistently wrote a secure version, but with the version of our task that confuses models, it then wrote vulnerable versions every time. This suggests that models like GPT-6.1-sol, as well as open models like Kimi K3 and Qwen3.8-Max, rely on memory just as much as Anthropic models do, even if the result is less visible.

How are the models recognizing code?

When we first noticed this phenomenon, although our findings already would cast doubt on the utility of evals such as SusVibes that rely on real-world code sources, it could still plausibly be explained by the idea that the surrounding code may have tipped the models off on what the codebase was. However, both frontier models and modern open models (from our testing, this is usually true for models above ~1.5T parameters, so models like Kimi K3 and Qwen3.8-Max) are incredibly proficient at recognizing increasingly obfuscated codebases just from the shape of the code.

Consider this fully obfuscated version of filters.py.

We renamed every name, replaced every string and number, removed comments, and shuffled every line into a random order. Yet Opus 5.5, Fable 5.2, and GPT-6.1-sol are still able to immediately recognize the codebase with 92-100% confidence.

CONFIDENCE: 100
REASON: The template filter registry, async variants, filesize formatting, attribute getters, and named-tuple grouping implementation uniquely match Jinja’s filters module.

Opus even explains its answer using names we never gave it, like make_attrgetter and _GroupTuple. It then recited its memorized code, but adapted it to fit the structure and style of the obfuscated codebase to maintain functionality. This suggests the issue extends far beyond just intact codebases, as any security eval that tries to sidestep the issue of models reciting memorized code by transforming the code still falls victim to these issues.

We tried various increasingly obfuscated methods, as shown in the bar graph above, but none of the methods we tried that preserved semantic equivalence consistently prevented models from recognizing and reciting code. Even when we compromised on semantic equivalence, methods such as shuffling functions could not consistently prevent the model from recognizing the codebase and, in some cases, reciting it.

The one thing that was common between every transformation we applied was that the underlying base was the same. So, we tried rewriting Jinja’s filters.py from scratch, using just a specification of how the behavior would work. This somewhat solved the issue of having models recite code from memory, but they were still able to recognize the codebase, which, as we explained earlier, is problematic.

So, we tried rewriting the code from scratch again. This time, we stripped all mentions of Jinja-related terms in our implementations, and we hid the implementation with completely generic names. The same vulnerabilities and general attack surface existed, but the context was completely different. Only then did models have truly no idea where the code was coming from, and thus had no ability to recite code from memory. However, this also decreased the model’s ability to write secure code. Without this recall, models wrote the target function with vulnerabilities every time (10/10 runs). We are currently working on running this experiment on more tasks, but we largely expect this to continue to hold true.

Although every model we tested with was able to recognize codebases in security evals with various levels of success, one stood out to us for its inclination to recite code from memory.

Which models are memorizing the code?

From our tests, we found the following:

Nearly every model we tested was able to pretty consistently recognize the codebase that SusVibes tasks were based on, even when we removed all references to the name of the repo (which evals such as SusVibes did not do). However, Anthropic models recited the code verbatim far more often than other models. We found it interesting that there was such a difference between OpenAI’s and Anthropic’s results, since we very rarely find such large objective differences between these models on identical prompts. The issue is not that OpenAI models didn’t recognize the code; when we rewrote Jinja from scratch (before we started confusing it), GPT-6.1-sol was able to identify the fix just as reliably as Opus 5.5. The model just recites code from memory less often. It’s hard to know what’s going on, but some plausible guesses include post-training that discourages reproducing training data verbatim, how we accessed the model, etc.

So how do we make better and more durable evals as model capabilities improve?

At its core, security evals are balancing three things:

1. Realism-How realistic are the vulnerabilities to real-world issues?
2. Transparency-Can anyone run and look at the tasks?
3. Durability-How likely are future models to memorize the answer?

It seems difficult to make a security eval that has all three. Evals based on real CVEs may be public and realistic, but their sources are not durable. Some of the synthetic evals we tried are public and somewhat more durable (although we saw signs of contamination, they were fixed much more easily than on real CVEs), but realism is lost. Private evals with new vulnerabilities for the purpose of judging model capabilities may be both realistic and durable, but they lose the ability for the general public to monitor the validity of their success.

We believe that trying to find some transform that magically causes models to be unable to recognize and thus recite codebases is a losing arms race. Back in 2025, when many of these evals were made, these strategies may have worked, but models have evolved to the point where these methods no longer suffice. There is no reason to believe the methods we use today will continue to work in the future as model capabilities continue to improve. What makes the issue more difficult is that as model capabilities continue to improve, it will likely become harder to tell when such recognition is taking place.

For now, we recommend making evals that are based on real-world vulnerabilities but are not full copies of real-world code. For example, taking a codebase and then adapting functions for a different context seems to work to keep most of the attack surface the same while still maintaining the same vulnerabilities and confusing a model’s capability to recognize the codebase. We ultimately believe that when weighting the three characteristics of a security eval, realism and durability are more important than the public being able to view evaluation tasks. Similar to how benchmarks like Humanity’s Last Exam [12] and ARC-AGI [13] have both a public dataset and a private held-out dataset, we believe security evals that offer such a structure provide the best compromise between remaining realistic and durable while still providing some degree of transparency.

Ultimately, we believe the best tasks are private synthetic tasks that use new vulnerabilities that have never been publicized. Such an eval would be high-effort, as writing good tasks is slow. But we believe that high-quality synthetic data is necessary for the future to prevent security evals from turning into memory tests.

Additional Information

More information about our experimental protocols and benchmarks, as well as the data behind some of our claims, will be published soon, as we want to spend additional time to make sure our facts are given proper care. This section will be edited with a link to our formal technical report when it’s up.

Code

Our code will also be published in the near future for the same reason as above. This section will be edited with a link when it’s up.
