{"id":"CVE-2026-27487","aliases":["GHSA-4564-pvr2-qq4h"],"url":"https://o3.security/vulnerability/CVE-2026-27487","summary":"OpenClaw: Prevent shell injection in macOS keychain credential write","details":"## Summary\nOn macOS, the Claude CLI keychain credential refresh path constructed a shell command to write the updated JSON blob into Keychain via `security add-generic-password -w ...`. Because OAuth tokens are user-controlled data, this created an OS command injection risk.\n\nThe fix avoids invoking a shell by using `execFileSync(\"security\", argv)` and passing the updated keychain payload as a literal argument.\n\n## Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Platform: macOS only\n- Affected versions: `<= 2026.2.13`\n\n## Fix\n- Patched version: `>= 2026.2.14` (next release)\n- Fix PR: #15924\n- Fix commits (merged to `main`):\n  - `9dce3d8bf83f13c067bc3c32291643d2f1f10a06`\n  - `66d7178f2d6f9d60abad35797f97f3e61389b70c`\n  - `b908388245764fb3586859f44d1dff5372b19caf`\n\nThanks @aether-ai-agent for reporting.","published":"2026-02-21T09:35:28.935Z","modified":"2026-08-12T03:51:32.767574353Z","cvss":{"score":7.6,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.14"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/66d7178f2d6f9d60abad35797f97f3e61389b70c","label":"openclaw/openclaw@66d7178"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/releases/tag/v2026.2.14"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27487.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-4564-pvr2-qq4h"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27487"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/66d7178f2d6f9d60abad35797f97f3e61389b70c"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/9dce3d8bf83f13c067bc3c32291643d2f1f10a06"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/b908388245764fb3586859f44d1dff5372b19caf"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/pull/15924"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:32.767574353Z"}}
