Pull request overview
This PR removes insecure pickle-based caching from the conversion engine optimizer script and replaces it with JSON serialization to prevent arbitrary code execution via malicious cache files.
Changes:
- Removed the
pickleimport and allpickle.dump/pickle.loadusage. - Implemented gzip-compressed JSON write/read for cached results via
json.dumps/json.loads.
🚨 Severity: CRITICAL
💡 Vulnerability: Insecure deserialization using
pickle.loadinscripts/optimize-conversion-engine.py.🎯 Impact: Arbitrary code execution if a malicious payload is supplied as a cache file.
🔧 Fix: Replaced
picklewithjsonfor serializing and deserializing cache data.✅ Verification: Ran
python scripts/optimize-conversion-engine.py --analyze-onlyand verified it executed without error. Also confirmed cache creation and reading mechanism withjson.PR created automatically by Jules for task 3957572072340927911 started by @anchapin
