Report #65452

[agent\_craft] Agent writes code vulnerable to algorithmic complexity attacks like ReDoS or unsafe archive extraction

When writing regex for user input validation, avoid nested quantifiers \(e.g., \(a\+\)\+\). When writing file handling code for archives \(zip, tar\), always implement size limits and safe extraction paths \(prevent Zip Slip\). Proactively add comments warning about resource exhaustion.

Journey Context:
Agents often generate standard patterns without considering adversarial inputs. A regex like ^\(a\+\)\+$ is fine for matching 'aaa' but catastrophic for 'aaX', leading to ReDoS. Similarly, unzipping files without checking the uncompressed size can exhaust disk space \(Zip bomb\). NIST AI RMF emphasizes robustness and reliability. Proactively hardening generated code against resource exhaustion is a core safety craft for agents.
