CVE-2025-67748 (GCVE-0-2025-67748)
Vulnerability from cvelistv5
Published

Modified
2025-12-16 21:12
Severity ?
7.1 (High) - CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P
CWE
  • CWE-184 - Incomplete List of Disallowed Inputs
  • CWE-502 - Deserialization of Untrusted Data
  • CWE-94 - Improper Control of Generation of Code ('Code Injection')
Summary
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.

CVE-2025-67747 (GCVE-0-2025-67747)
Vulnerability from cvelistv5
Published
2025-12-16 00:32
Modified
2025-12-16 20:05
Severity ?
7.1 (High) - CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P
CWE
  • CWE-184 - Incomplete List of Disallowed Inputs
  • CWE-502 - Deserialization of Untrusted Data
Summary
Fickling is a Python pickling decompiler and static analyzer. Versions prior to 0.1.6 are missing `marshal` and `types` from the block list of unsafe module imports. Fickling started blocking both modules to address this issue. This allows an attacker to craft a malicious pickle file that can bypass fickling since it misses detections for `types.FunctionType` and `marshal.loads`. A user who deserializes such a file, believing it to be safe, would inadvertently execute arbitrary code on their system. This impacts any user or system that uses Fickling to vet pickle files for security issues. The issue was fixed in version 0.1.6.
