When tools.message.crossContext.allowWithinProvider is disabled, an admitted (authenticated) sender can remove a pin from another Feishu group that the sender and the configured account are otherwise permitted to access, bypassing the intended cross-context message mutation policy. Feishu membership and group authorization still apply, and the demonstrated impact is limited to message mutation (pin removal). The issue is fixed in 2026.8.1.","categories":["Unclassified"],"product":"OpenClaw","vendor":"OpenClaw","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100553","source_modified_at":"2026-09-29T17:10:13.838Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"OpenClaw","vendor":"OpenClaw","versions":[{"version":"2026.6.9","status":"affected","versionType":"semver","lessThan":"2026.8.1"},{"version":"2026.8.1","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100553","source_modified_at":"2026-09-29T17:10:13.838Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"OpenClaw","ecosystem":null},"version":"2026.8.1","basis":"first unaffected version stated in the CVE record"}],"cvss":5.3,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00215,"percentile":0.11319,"score_date":"2026-10-23"},"published_at":"2026-09-26T02:18:48.240Z","modified_at":"2026-09-29T17:10:13.838Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-100553","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-29T17:10:13.838Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-100553","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-h9jh-75j7-7hhx","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/openclaw-2026.6.9-before-2026.8.1-cross-context-policy-bypass-via-feishu-unpin","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-29T17:09:47.857552Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-29T17:10:13.838Z","content_hash":"1c112caad03ea931f2a12854126511f37e6ad28918bc37e9f8950212242fcf99"}}
