{"id":"GHSA-f7ww-2725-qvw2","summary":"OpenClaw: Node system.run approval bypass via parent-symlink cwd rebind","details":"## Summary\nFor `host=node` executions, approval context could be bypassed after approval-time by rebinding a writable parent symlink in `cwd` while preserving the visible `cwd` string.\n\n## Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Affected: `\u003c= 2026.2.25`\n- Fixed: `\u003e= 2026.2.26` (planned next npm release)\n\n## Impact\nA command approved for one filesystem location could execute from a different location if a mutable parent symlink changed between approval and execution.\n\n## Fix\n- Added immutable approval-time plan preparation (`system.run.prepare`) and `systemRunPlanV2` canonical fields (`argv`, `cwd`, `agentId`, `sessionKey`).\n- Enforced canonical plan values through approval request storage and forwarding-time sanitization.\n- Rejected mutable parent-symlink path components during approval-plan building to block symlink rebind bypass.\n- Follow-up refactors centralized command catalogs and approval context/error handling to reduce future drift.\n\n## Fix Commit(s)\n- `78a7ff2d50fb3bcef351571cb5a0f21430a340c1`\n- `d82c042b09727a6148f3ca651b254c4a677aff26`\n- `d06632ba45a8482192792c55d5ff0b2e21abb0a7`\n- `4e690e09c746408b5e27617a20cb3fdc5190dbda`\n- `4b4718c8dfce2e2c48404aa5088af7c013bed60b`\n\n## Release Process Note\n`patched_versions` is pre-set to the planned next release (`2026.2.26`). Once npm `openclaw@2026.2.26` is published, publish this advisory directly without further version-field edits.\n\nOpenClaw thanks @tdjackey for reporting.","aliases":["CVE-2026-27545"],"modified":"2026-03-18T22:01:33.472977Z","published":"2026-03-02T23:35:56Z","database_specific":{"cwe_ids":["CWE-367","CWE-59"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-03-02T23:35:56Z","nvd_published_at":"2026-03-18T02:16:23Z"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-f7ww-2725-qvw2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27545"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/4b4718c8dfce2e2c48404aa5088af7c013bed60b"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/4e690e09c746408b5e27617a20cb3fdc5190dbda"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/78a7ff2d50fb3bcef351571cb5a0f21430a340c1"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/d06632ba45a8482192792c55d5ff0b2e21abb0a7"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/d82c042b09727a6148f3ca651b254c4a677aff26"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-approval-bypass-via-parent-symlink-current-working-directory-rebind"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.2.26"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-f7ww-2725-qvw2/GHSA-f7ww-2725-qvw2.json","last_known_affected_version_range":"\u003c= 2026.2.25"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
