{"id":"CVE-2026-100553","summary":"OpenClaw 2026.6.9 before 2026.8.1 Cross-Context Policy Bypass via Feishu unpin","details":"OpenClaw versions \u003e= 2026.6.9 and \u003c 2026.8.1 do not declare the native chatId parameter as a delivery target in the Feishu unpin feature, so unpin requests can bypass the shared same-provider cross-context target check. 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.","aliases":["GHSA-h9jh-75j7-7hhx"],"modified":"2026-09-30T03:31:06.426587942Z","published":"2026-09-26T02:18:48.240Z","database_specific":{"cwe_ids":["CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/100xxx/CVE-2026-100553.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/100xxx/CVE-2026-100553.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-h9jh-75j7-7hhx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-100553"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-2026.6.9-before-2026.8.1-cross-context-policy-bypass-via-feishu-unpin"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openclaw/openclaw","events":[{"introduced":"c645ec4555c017931de0e35ad9847dffae2741ef"},{"fixed":"ea806575e6450e4d1efdfc72c19f04be982a1b9b"}],"database_specific":{"extracted_events":[{"introduced":"2026.6.9"},{"fixed":"2026.8.1"}],"source":"AFFECTED_FIELD"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-100553.json"}}],"schema_version":"1.9.0","severity":[{"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"}]}
