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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Important · affected: Red Hat OpenShift Dev Spaces · no fix planned: Red Hat OpenShift Dev Spaces · updated 2026-10-13 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-86063.json)\n\n## Package advisory (CVE-2026-86063)\n\nAffected packages:\n\n- `@anthropic-ai/claude-code < 2.1.179`\n\nPatched in:\n\n- `@anthropic-ai/claude-code 2.1.179`\n\nSource: https://github.com/advisories/GHSA-pq7j-f95f-qfcv","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":48.4,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":220100,"id":"CVE-2026-86063","ts":1791978537718,"field":"cvss","old":null,"new":"8.8"},{"seq":220099,"id":"CVE-2026-86063","ts":1791978537718,"field":"severity","old":"none","new":"high"}]}
