Prior to 2.1.179, the Claude Code and Claude Desktop plugin installation flow runs git checkout for a marketplace-pinned commit without verifying that the resulting HEAD equals the pinned 40-character SHA. An attacker who controls a plugin repository on a Git host that permits SHA-shaped branch names can create a branch named after the reviewed commit, causing checkout to select the branch tip and install attacker-controlled plugin code. Exploitation requires a user to install the malicious plugin and pin it to the ostensibly safe hash. This issue is fixed in version 2.1.179.","state":0,"publishedAt":"2026-10-13T19:21:21.417+00:00","modifiedAt":"2026-10-13T21:19:36.73+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":7.5,"severity":"HIGH"}],"references":["https://github.com/anthropics/claude-code/releases/tag/v2.1.179","https://github.com/anthropics/claude-code/security/advisories/GHSA-pq7j-f95f-qfcv"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-86063","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-494","CWE-829"],"productCriteria":[],"sourceDates":{"published":"2026-10-13T19:21:21.417","lastModified":"2026-10-13T21:19:36.730"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
