{"cve":"CVE-2026-22607","nvd":{"published":"2026-01-10T02:15:49.780","modified":"2026-06-17T10:20:09.220","status":"Analyzed","description":"Fickling is a Python pickling decompiler and static analyzer. Fickling versions up to and including 0.1.6 do not treat Python's cProfile module as unsafe. Because of this, a malicious pickle that uses cProfile.run() 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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P","score":8.9},"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-184","CWE-502"],"references":["https://github.com/trailofbits/fickling/commit/dc8ae12966edee27a78fe05c5745171a2b138d43","https://github.com/trailofbits/fickling/releases/tag/v0.1.7","https://github.com/trailofbits/fickling/security/advisories/GHSA-p523-jq9w-64x9","https://github.com/trailofbits/fickling/security/advisories/GHSA-p523-jq9w-64x9"],"products":["trailofbits:fickling"],"source":"nvd","synced_at":"2026-10-19T22:19:41.481987139+00:00"},"epss":{"cve":"CVE-2026-22607","score":0.00522,"percentile":0.44322,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-p523-jq9w-64x9","url":"https://osv.dev/vulnerability/GHSA-p523-jq9w-64x9","summary":"Fickling Blocklist Bypass: cProfile.run()","modified":"2026-07-07T17:57:35.815098015Z","packages":[{"ecosystem":"PyPI","name":"fickling","purl":"pkg:pypi/fickling","ranges":["<0.1.7"],"fixed":["0.1.7"]}]},{"id":"PYSEC-2026-1371","url":"https://osv.dev/vulnerability/PYSEC-2026-1371","summary":"Fickling Blocklist Bypass: cProfile.run()","modified":"2026-07-07T17:47:13.994881204Z","packages":[{"ecosystem":"PyPI","name":"fickling","purl":"pkg:pypi/fickling","ranges":["<0.1.7"],"fixed":["0.1.7"]}]}],"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).
