{"id":"CVE-2026-22606","published":"2026-01-10T01:35:00Z","modified":"2026-01-13T19:58:14Z","title":"Fickling has a bypass via runpy.run_path() and runpy.run_module()","vendor":"trailofbits","product":"fickling","tier":"tail","description":{"text":"Fickling is a Python pickling decompiler and static analyzer. Fickling versions up to and including 0.1.6 do not treat Python’s runpy module as unsafe. Because of this, a malicious pickle that uses runpy.run_path() or runpy.run_module() 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.","provenance":"source","from":"CVE.org"},"cvss":{"score":8.9,"severity":"HIGH","version":"4.0","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","provenance":"source","from":"CVE.org CNA"},"epss":{"score":0.00482,"percentile":0.41451,"provenance":"source"},"cwes":[{"id":"CWE-184","name":"Incomplete List of Disallowed Inputs"},{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"references":[{"url":"https://github.com/trailofbits/fickling/security/advisories/GHSA-wfq2-52f7-7qvj","tags":["x_refsource_CONFIRM"]},{"url":"https://github.com/trailofbits/fickling/commit/9a2b3f89bd0598b528d62c10a64c1986fcb09f66","tags":["x_refsource_MISC"]},{"url":"https://github.com/trailofbits/fickling/releases/tag/v0.1.7","tags":["x_refsource_MISC"]}],"priority":{"score":14.5,"factors":[{"name":"EPSS percentile","points":8.29},{"name":"CVSS severity","points":6.23}]},"vendorSlug":"trailofbits","affectedVersions":[{"vendor":"trailofbits","product":"fickling","versions":["< 0.1.7"]}],"affected":[{"ecosystem":"PyPI","package":"fickling","vulnerableRanges":["<0.1.7"],"patched":["0.1.7"],"from":["GHSA-wfq2-52f7-7qvj","PYSEC-2026-1373"],"provenance":"source"}],"euvd":{"id":"EUVD-2026-1688","exploited":false,"provenance":"source"},"lineage":{"familyId":"fam-trailofbits-fickling-cve-2025-67747","parents":[{"from":"CVE-2025-67747","to":"CVE-2026-22606","relation":"related","confidence":"high","kind":"lineage","evidence":[{"kind":"osv-related","provenance":"source","id":"GHSA-wfq2-52f7-7qvj","via":"reference","url":"https://github.com/trailofbits/fickling/security/advisories/GHSA-565g-hwwr-4pp3"},{"kind":"osv-related","provenance":"source","id":"PYSEC-2026-1373","via":"reference","url":"https://github.com/trailofbits/fickling/security/advisories/GHSA-565g-hwwr-4pp3"}]},{"from":"CVE-2025-67748","to":"CVE-2026-22606","relation":"related","confidence":"high","kind":"lineage","evidence":[{"kind":"osv-related","provenance":"source","id":"GHSA-wfq2-52f7-7qvj","via":"reference","url":"https://github.com/trailofbits/fickling/security/advisories/GHSA-r7v6-mfhq-g3m2"},{"kind":"osv-related","provenance":"source","id":"PYSEC-2026-1373","via":"reference","url":"https://github.com/trailofbits/fickling/security/advisories/GHSA-r7v6-mfhq-g3m2"}]}]}}
