{"id":"GHSA-wm8r-w8pf-2v6w","summary":"OpenClaw has Signal group allowlist authorization bypass via DM pairing-store leakage","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: `\u003c= 2026.2.25`\n- Patched version (planned next release): `\u003e= 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.","aliases":["CVE-2026-31991"],"modified":"2026-03-20T22:11:22.662622Z","published":"2026-03-02T22:14:56Z","database_specific":{"nvd_published_at":null,"cwe_ids":["CWE-863"],"severity":"LOW","github_reviewed":true,"github_reviewed_at":"2026-03-02T22:14:56Z"},"references":[{"type":"WEB","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":"WEB","url":"https://github.com/openclaw/openclaw/commit/64de4b6d6ae81e269ceb4ca16f53cda99ced967a"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/8bdda7a651c21e98faccdbbd73081e79cffe8be0"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-authorization-bypass-via-dm-pairing-store-leakage-in-signal-group-allowlist"}],"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-wm8r-w8pf-2v6w/GHSA-wm8r-w8pf-2v6w.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:N"}]}
