{"id":"GHSA-792q-qw95-f446","summary":"OpenClaw's Signal reaction-only status events could, in limited cases, be enqueued before access checks","details":"### Summary\nIn a narrow Signal reaction-notification path, reaction-only inbound events could enqueue a status event before sender access checks were applied.\n\n### Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Affected: `\u003c= 2026.2.24` (latest published at patch time)\n- Fixed: `2026.2.25` \n\n### Details\nIn the affected flow (`src/signal/monitor/event-handler.ts`), reaction-only handling could return after `enqueueSystemEvent(...)` before DM/group authorization checks were evaluated for that sender.\n\nThis behavior was limited to reaction-only inbound events with reaction notifications enabled. In that case, a sender not authorized for normal DM flow could still queue a Signal reaction status line for that session.\n\nThe fix applies shared DM/group access checks before reaction notification enqueue. Pairing behavior for normal DM messages is unchanged.\n\n### Impact\n- Limited to Signal reaction-only inbound events.\n- Could add an unauthorized reaction status line to agent context for affected sessions.\n- Did not directly enable normal DM delivery or direct host command execution.\n\n### Fix Commit(s)\n- `2aa7842adeedef423be7ce283a9144b9f1a0a669`\n\n### Release Process Note\n`patched_versions` is pre-set to `2026.2.25` so once npm release is out, advisory publish can proceed directly.\n\nOpenClaw thanks @tdjackey for reporting.","aliases":["CVE-2026-32050"],"modified":"2026-03-30T13:56:22.717479Z","published":"2026-03-03T23:11:47Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-03-03T23:11:47Z","nvd_published_at":null,"cwe_ids":["CWE-863"],"severity":"MODERATE"},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-792q-qw95-f446"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32050"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/2aa7842adeedef423be7ce283a9144b9f1a0a669"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-unauthorized-reaction-status-event-enqueue-via-access-check-bypass"}],"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-792q-qw95-f446/GHSA-792q-qw95-f446.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
