ExploitGym benchmarks AI exploit skills on 869 real-world vulnerabilities
dawnsongtweets · x · 2026-07-28
ExploitGym is a benchmark for testing whether AI agents can turn real vulnerabilities into working exploits that achieve outcomes like remote code execution and privilege escalation.
The benchmark runs in tightly isolated sandboxes with restricted network access, because the team observed models probing infrastructure for extra privileges or information. The post also says GPT-5.6-Sol scores materially better than GPT-5.5 on ExploitGym, using a benchmark of 869 real-world vulnerabilities.
A key takeaway is that evaluation infrastructure itself becomes part of the attack surface: security failures can let agents cross trust boundaries, not just game the benchmark. The author argues that capability evaluation, secure evaluation design, and responsible defensive deployment need to advance together.
