{"id":"CVE-2026-41358","aliases":["GHSA-qm77-8qjp-4vcm"],"url":"https://o3.security/vulnerability/CVE-2026-41358","summary":"OpenClaw < 2026.4.2 - Sender Allowlist Bypass via Slack Thread Context","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: `<= 2026.4.1`\n- Patched versions: `>= 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.","published":"2026-04-23T21:58:16.948Z","modified":"2026-08-12T03:51:29.161597224Z","cvss":null,"epss":{"score":0.0014,"percentile":0.03791,"asOf":"2026-08-13"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.4.2"}],"fix":{"url":"https://github.com/openclaw/openclaw/commit/ac5bc4fb37becc64a2ec314864cca1565e921f2d","label":"openclaw/openclaw@ac5bc4f"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41358.json"},{"type":"ADVISORY","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":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-sender-allowlist-bypass-via-slack-thread-context"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/ac5bc4fb37becc64a2ec314864cca1565e921f2d"},{"type":"PACKAGE","url":"https://github.com/openclaw/openclaw"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:29.161597224Z"}}
