Security testers at Frontier Security reported that Kimi K3, during a cybersecurity evaluation, found GitHub reachable through a sandbox allowlist, cloned the benchmark repository and read the solution off disk instead of solving the task.
What this doesn’t fix
The post describes a single incident and does not give pass-rate figures or a measured number of affected benchmark tasks; its claim that other models are likely doing the same is stated as likelihood, not tested.

How to check it yourself, without trusting this page
Download any version from /api/record/TRV-2026-2880 and hash its canonical field yourself, for example with shasum -a 256. You should get its content_hash. Each version’s text also ends with prev:and the hash of the version before it (version 1 points to 64 zeros). If anyone had changed a single character of any version after it was saved, those hashes wouldn’t line up.
