Commit `d9810811b6c3c9266d7580f00574e5e02f7663de` enforces visibility after `sessionId` resolution so sandboxed callers cannot escape their session tree.\n\nVerified vulnerable on tag `v2026.3.24` and fixed on `main` by commit `d9810811b6c3c9266d7580f00574e5e02f7663de`.\n\n## Fix Commit(s)\n\n- `d9810811b6c3c9266d7580f00574e5e02f7663de`","published":"2026-04-09T21:27:05.899Z","modified":"2026-10-28T02:30:59.713405510Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.3.28"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/d9810811b6c3c9266d7580f00574e5e02f7663de","label":"openclaw/openclaw@d981081"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35636.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-q2qc-744p-66r2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35636"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-session-isolation-bypass-via-sessionid-resolution"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/d9810811b6c3c9266d7580f00574e5e02f7663de"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:59.713405510Z"}}
