{"id":"CVE-2026-27523","aliases":["GHSA-m8v2-6wwh-r4gc"],"url":"https://o3.security/vulnerability/CVE-2026-27523","summary":"OpenClaw < 2026.2.24 - Sandbox Bind Validation Bypass via Symlink-Parent Missing-Leaf Paths","details":"OpenClaw versions prior to 2026.2.24 contain a sandbox bind validation vulnerability allowing attackers to bypass allowed-root and blocked-path checks via symlinked parent directories with non-existent leaf paths. Attackers can craft bind source paths that appear within allowed roots but resolve outside sandbox boundaries once missing leaf components are created, weakening bind-source isolation enforcement.","published":"2026-03-18T01:34:27.047Z","modified":"2026-08-09T03:46:09.722133393Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.24"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/b5787e4abba0dcc6baf09051099f6773c1679ec1","label":"openclaw/openclaw@b5787e4"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27523.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-m8v2-6wwh-r4gc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27523"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-sandbox-bind-validation-bypass-via-symlink-parent-missing-leaf-paths"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/b5787e4abba0dcc6baf09051099f6773c1679ec1"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-09T03:46:09.722133393Z"}}
