{"cve":"CVE-2025-67748","nvd":{"published":"2025-12-16T01:15:52.950","modified":"2026-10-07T19:10:00.160","status":"Analyzed","description":"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.","cvss_v4":{"vector":"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","score":7.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-94","CWE-184","CWE-502"],"references":["https://github.com/trailofbits/fickling/pull/108","https://github.com/trailofbits/fickling/pull/187","https://github.com/trailofbits/fickling/security/advisories/GHSA-r7v6-mfhq-g3m2"],"products":["trailofbits:fickling"],"source":"nvd","synced_at":"2026-10-19T22:17:07.138532058+00:00"},"epss":{"cve":"CVE-2025-67748","score":0.0027,"percentile":0.18976,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-r7v6-mfhq-g3m2","url":"https://osv.dev/vulnerability/GHSA-r7v6-mfhq-g3m2","summary":"Fickling has Code Injection vulnerability via pty.spawn()","modified":"2026-06-05T18:00:13.871352009Z","packages":[{"ecosystem":"PyPI","name":"fickling","purl":"pkg:pypi/fickling","ranges":["<0.1.6"],"fixed":["0.1.6"]}]},{"id":"PYSEC-2025-113","url":"https://osv.dev/vulnerability/PYSEC-2025-113","summary":"","modified":"2026-05-20T09:19:00.310433Z","packages":[{"ecosystem":"PyPI","name":"fickling","purl":"pkg:pypi/fickling","ranges":["<0.1.6"],"fixed":["0.1.6"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
