FKIE_CVE-2026-22608
Vulnerability from fkie_nvd - Published: 2026-01-10 02:15 - Updated: 2026-01-16 18:57
Severity
Summary
Fickling is a Python pickling decompiler and static analyzer. Prior to version 0.1.7, both ctypes and pydoc modules aren't explicitly blocked. Even other existing pickle scanning tools (like picklescan) do not block pydoc.locate. Chaining these two together can achieve RCE while the scanner still reports the file as LIKELY_SAFE. This issue has been patched in version 0.1.7.
