A sender that has been explicitly denied filesystem read tools can still cause a known local file to be read and returned via a final-response media directive or a message attachment, disclosing local file contents to an admitted requester whose agent turn did not include the read tool. Exploitation requires knowledge or derivation of a useful host path and a delivery flow that accepts local attachments. The issue is fixed in version 2026.8.1.","state":0,"publishedAt":"2026-09-26T02:18:37.196+00:00","modifiedAt":"2026-09-28T17:44:58.113+00:00","affected":[{"ecosystem":"Vendor product","name":"OpenClaw","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"OpenClaw\",\n                    \"product\": \"OpenClaw\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:npm/openclaw\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"2026.8.1\"\n                        },\n                        {\n                            \"version\": \"2026.8.1\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":7.1,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/openclaw/openclaw/security/advisories/GHSA-w5x7-c87m-3jpc","https://www.vulncheck.com/advisories/openclaw-before-2026.8.1-local-file-read-via-outbound-attachments"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-100538","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-100538","identifiers":["CVE-2026-100538"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
