{"id":"CVE-2026-31991","aliases":["GHSA-wm8r-w8pf-2v6w"],"url":"https://o3.security/vulnerability/CVE-2026-31991","summary":"OpenClaw < 2026.2.26 - Authorization Bypass via DM Pairing-Store Leakage in Signal Group Allowlist","details":"### Summary\nIn OpenClaw `2026.2.25`, Signal group authorization under `groupPolicy=allowlist` could accept sender identities sourced from DM pairing-store approvals. This allowed DM pairing approvals to leak into group allowlist evaluation.\n\n### Impact\nThis is an authorization-boundary weakness between DM pairing and group allowlist controls. A sender approved for DM pairing could pass group checks without explicit group allowlisting.\n\n### Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Latest published version affected: `2026.2.25`\n- Vulnerable range: `<= 2026.2.25`\n- Patched version (planned next release): `>= 2026.2.26`\n\n### Fix\nOpenClaw now keeps DM pairing-store entries DM-only and enforces explicit group allowlist boundaries in shared DM/group policy resolution used by Signal and other channels.\n\n### Fix Commit(s)\n- `8bdda7a651c21e98faccdbbd73081e79cffe8be0`\n- `64de4b6d6ae81e269ceb4ca16f53cda99ced967a`\n\n### Release Process Note\n`patched_versions` is pre-set to the planned next release (`2026.2.26`). After npm publish of that version, this advisory is ready to publish without further content edits.\n\nThanks @tdjackey for reporting.","published":"2026-03-19T01:00:50.508Z","modified":"2026-10-28T02:30:48.420537423Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.26"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/64de4b6d6ae81e269ceb4ca16f53cda99ced967a","label":"openclaw/openclaw@64de4b6"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31991.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-wm8r-w8pf-2v6w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31991"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-authorization-bypass-via-dm-pairing-store-leakage-in-signal-group-allowlist"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/64de4b6d6ae81e269ceb4ca16f53cda99ced967a"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/8bdda7a651c21e98faccdbbd73081e79cffe8be0"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:48.420537423Z"}}
