PYSEC-2025-113
No affected components available
Fickling is a Python pickling decompiler and static analyzer. Versions prior to 0.1.6 had a bypass caused by pty missing from the block list of unsafe module imports. This led to unsafe pickles based on pty.spawn() being incorrectly flagged as LIKELY_SAFE, and was fixed in version 0.1.6. This impacted any user or system that used Fickling to vet pickle files for security issues.
