CVE-2026-22609

Fickling is a Python pickling decompiler and static analyzer. Prior to version 0.1.7, the unsafeimports method in Fickling's static analyzer fails to flag several high-risk Python modules that can be used for arbitrary code execution. Malicious pickles importing these modules will not be detected...

CVE-2026-22607

Fickling is a Python pickling decompiler and static analyzer. Fickling versions up to and including 0.1.6 do not treat Python's cProfile module as unsafe. Because of this, a malicious pickle that uses cProfile.run is classified as SUSPICIOUS instead of OVERTLYMALICIOUS. If a user relies on...

CVE-2026-22607

Summary (CVE-2026-22607 – Fickling) Fickling (Python pickling decompiler/static analyzer) versions up to and including 0.1.6 fail to treat the Python module cProfile as unsafe. This causes a malicious pickle using cProfile.run() to be classified as SUSPICIOUS rather than OVERTLY_MALICIOUS, potent...

CVE-2026-22607 Fickling Blocklist Bypass: cProfile.run()

Fickling is a Python pickling decompiler and static analyzer. Fickling versions up to and including 0.1.6 do not treat Python's cProfile module as unsafe. Because of this, a malicious pickle that uses cProfile.run is classified as SUSPICIOUS instead of OVERTLYMALICIOUS. If a user relies on...

CVE-2026-22606

CVE-2026-22606 affects Fickling (Python pickling decompiler/static analyzer) up to version 0.1.6. The root cause is that the runpy module (including run_path and run_module) was not treated as unsafe, causing some malicious pickles to be classified as SUSPICIOUS rather than OVERTLY_MALICIOUS. Thi...
