CVE-2026-22608Public exploitNetwork attack vector

Code execution via unblocked pydoc and ctypes imports

Published Jan 10, 2026 · Updated Jan 10, 2026

Code execution in the unsafe-import analyzer in Trail of Bits Fickling before 0.1.7 allows attackers to run code via a crafted pickle file. The unsafe_imports analysis omits pydoc and ctypes, so pydoc.locate resolves a native execution function while the payload remains rated LIKELY_SAFE. The attacker must cause a Fickling-protected workflow to accept and later load the crafted pickle, which executes with that workflow's privileges.
