{"id":"GHSA-qm77-8qjp-4vcm","summary":"OpenClaw: Slack thread context could include messages from non-allowlisted senders","details":"## Summary\n\nBefore OpenClaw 2026.4.2, Slack thread starter and thread-history context fetched through the API was not filtered by the effective sender allowlist. Messages from non-allowlisted senders could still enter the agent context when an allowlisted user replied in the same thread.\n\n## Impact\n\nA Slack deployment that relied on sender allowlists could still feed non-allowlisted thread content into the model context through thread history. This was a sender-access-control bypass on Slack thread context, not a direct channel-auth bypass.\n\n## Affected Packages / Versions\n\n- Package: `openclaw` (npm)\n- Affected versions: `\u003c= 2026.4.1`\n- Patched versions: `\u003e= 2026.4.2`\n- Latest published npm version: `2026.4.1`\n\n## Fix Commit(s)\n\n- `ac5bc4fb37becc64a2ec314864cca1565e921f2d` — filter Slack thread context by the effective allowlist\n\n## Release Process Note\n\nThe fix is present on `main` and is staged for OpenClaw `2026.4.2`. Publish this advisory after the `2026.4.2` npm release is live.\n\nOpenClaw thanks @AntAISecurityLab for reporting.","aliases":["CVE-2026-41358"],"modified":"2026-05-05T16:26:33.664502Z","published":"2026-05-04T16:52:21Z","database_specific":{"cwe_ids":["CWE-346"],"severity":"LOW","github_reviewed":true,"github_reviewed_at":"2026-05-04T16:52:21Z","nvd_published_at":null},"references":[{"type":"WEB","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-qm77-8qjp-4vcm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41358"},{"type":"WEB","url":"https://github.com/openclaw/openclaw/commit/ac5bc4fb37becc64a2ec314864cca1565e921f2d"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openclaw-sender-allowlist-bypass-via-slack-thread-context"}],"affected":[{"package":{"name":"openclaw","ecosystem":"npm","purl":"pkg:npm/openclaw"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2026.4.2"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 2026.4.1","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-qm77-8qjp-4vcm/GHSA-qm77-8qjp-4vcm.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
