{"cve":"CVE-2026-22609","nvd":{"published":"2026-01-10T02:15:50.050","modified":"2026-06-17T10:20:09.460","status":"Analyzed","description":"Fickling is a Python pickling decompiler and static analyzer. Prior to version 0.1.7, the unsafe_imports() method in Fickling's static analyzer fails to flag several high-risk Python modules that can be used for arbitrary code execution. Malicious pickles importing these modules will not be detected as unsafe, allowing attackers to bypass Fickling's primary static safety checks. 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/29d5545e74b07766892c1f0461b801afccee4f91","https://github.com/trailofbits/fickling/commit/9a2b3f89bd0598b528d62c10a64c1986fcb09f66","https://github.com/trailofbits/fickling/commit/b793563e60a5e039c5837b09d7f4f6b92e6040d1","https://github.com/trailofbits/fickling/commit/eb299b453342f1931c787bcb3bc33f3a03a173f9","https://github.com/trailofbits/fickling/releases/tag/v0.1.7"],"products":["trailofbits:fickling"],"source":"nvd","synced_at":"2026-10-19T22:19:41.481987139+00:00"},"epss":{"cve":"CVE-2026-22609","score":0.00629,"percentile":0.50145,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-q5qq-mvfm-j35x","url":"https://osv.dev/vulnerability/GHSA-q5qq-mvfm-j35x","summary":"Fickling has Static Analysis Bypass via Incomplete Dangerous Module Blocklist","modified":"2026-07-07T17:57:31.947656111Z","packages":[{"ecosystem":"PyPI","name":"fickling","purl":"pkg:pypi/fickling","ranges":["<0.1.7"],"fixed":["0.1.7"]}]},{"id":"PYSEC-2026-1372","url":"https://osv.dev/vulnerability/PYSEC-2026-1372","summary":"Fickling has Static Analysis Bypass via Incomplete Dangerous Module Blocklist","modified":"2026-07-07T17:47:14.888738770Z","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).
