{"id":"CVE-2026-32977","aliases":["GHSA-xvx8-77m6-gwg6"],"url":"https://o3.security/vulnerability/CVE-2026-32977","summary":"OpenClaw < 2026.3.11 - Sandbox Boundary Bypass via Unanchored writeFile Commit Path","details":"## Summary\nIn affected versions of `openclaw`, the sandbox fs-bridge `writeFile` commit step used an unanchored container path during the final move into place. An attacker racing parent-path changes inside the sandbox could redirect the committed file outside the validated sandbox path.\n\n## Impact\nThis is a sandbox boundary bypass. In-sandbox code could win a time-of-check-time-of-use race and cause host-approved `writeFile` operations to land outside the validated writable path within the container mount namespace.\n\n## Affected Packages and Versions\n- Package: `openclaw` (npm)\n- Affected versions: `< 2026.3.11`\n- Fixed in: `2026.3.11`\n\n## Technical Details\nThe hardening work for anchored remove, rename, and mkdir operations did not fully cover the `writeFile` commit path. The final `mv` still used the raw target path, leaving a race window between safety revalidation and the in-container commit step.\n\n## Fix\nOpenClaw now anchors the `writeFile` commit path to the canonical parent directory before the final move. The fix shipped in `openclaw@2026.3.11`.\n\n## Workarounds\nUpgrade to `2026.3.11` or later.","published":"2026-03-31T11:17:18.684Z","modified":"2026-08-17T03:54:57.639069454Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.3.11"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32977.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-xvx8-77m6-gwg6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32977"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-sandbox-boundary-bypass-via-unanchored-writefile-commit-path"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/releases/tag/v2026.3.11"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-17T03:54:57.639069454Z"}}
