CVE-2026-22606 (GCVE-0-2026-22606)

Vulnerability from cvelistv5 – Published: 2026-01-10 01:35 – Updated: 2026-01-13 19:58

Title
Fickling has a bypass via runpy.run_path() and runpy.run_module()
Summary
Fickling is a Python pickling decompiler and static analyzer. Fickling versions up to and including 0.1.6 do not treat Python’s runpy module as unsafe. Because of this, a malicious pickle that uses runpy.run_path() or runpy.run_module() is classified as SUSPICIOUS instead of OVERTLY_MALICIOUS. If a user relies on Fickling’s output to decide whether a pickle is safe to deserialize, this misclassification can lead them to execute attacker-controlled code on their system. This affects any workflow or product that uses Fickling as a security gate for pickle deserialization. This issue has been patched in version 0.1.7.
