{"id":"GHSA-rm2p-j3r7-4x4j","summary":"OpenClaw's Slack reaction/pin sender-policy consistency issue in non-message ingress","details":"### Summary\nOpenClaw Slack monitor handled `reaction_*` and `pin_*` non-message events before applying sender-policy checks consistently.\n\nIn affected versions, these events could be added to system-event context even when sender policy would not normally allow them.\n\n### Affected Packages / Versions\n- Package: npm `openclaw`\n- Latest published affected version confirmed: `2026.2.24` (npm latest as of February 26, 2026)\n- Affected range: `\u003c= 2026.2.24`\n- Patched version : `2026.2.25`\n\n### Technical Details\n- `reaction_*` and `pin_*` handlers now route through shared sender authorization (`authorizeSlackSystemEventSender`).\n- Enforced checks now include:\n  - DM `dmPolicy` / `allowFrom`\n  - channel `users` allowlist enforcement for non-DM channels\n  - channel-level allow checks before system-event enqueue\n- Regression coverage added for DM allow/deny and channel-user allowlist deny paths.\n\n### Fix Commit(s)\n- `aedf62ac7e669a89c7b299201bf6537dc6b12e0e`\n- `75dfb71e4e8b7c2feba5a8ca662f92ea840e0147`\n\n### Impact\nLow-severity policy-consistency issue in Slack non-message event ingress.\nThis may introduce unexpected reaction/pin context signals from senders outside configured policy.\n\n### Release Process Note\n`patched_versions` is pre-set to planned release `2026.2.25`. Advisory published with npm release `2026.2.25`.\n\nOpenClaw thanks @tdjackey for reporting.","aliases":["CVE-2026-32899"],"modified":"2026-03-30T14:11:33.485794Z","published":"2026-03-03T19:50:26Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-03-03T19:50:26Z","nvd_published_at":null,"cwe_ids":["CWE-863"]},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-rm2p-j3r7-4x4j"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32899"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/75dfb71e4e8b7c2feba5a8ca662f92ea840e0147"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/aedf62ac7e669a89c7b299201bf6537dc6b12e0e"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-sender-policy-bypass-in-slack-reaction-and-pin-event-handlers"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.2.25"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 2026.2.24","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-rm2p-j3r7-4x4j/GHSA-rm2p-j3r7-4x4j.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
