{"id":"CVE-2026-100547","published":"2026-09-26T03:17:00.890","lastModified":"2026-09-28T15:23:38.510","description":"OpenClaw is a coding agent distributed as the npm package `openclaw`. In affected versions (2026.7.1 through 2026.7.2), alternate but valid `file:` URL spellings supplied over the Agent Client Protocol (ACP) were treated as relative paths and were incorrectly classified as reads scoped to the session working directory. When an operator connected `openclaw acp client` to an untrusted or compromised ACP peer, that peer could request a read of a file outside the session working directory without the approval prompt normally required for that path, resulting in disclosure of local file contents. The demonstrated impact is limited to file confidentiality; mutating and command-capable tool classes are not affected. This issue is fixed in OpenClaw 2026.8.1.","cvssScore":5.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","cwes":["CWE-180"],"vendors":[],"products":[],"references":[{"url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-356g-m7rx-7pm3","tags":[]},{"url":"https://www.vulncheck.com/advisories/openclaw-before-2026.8.1-authentication-bypass-via-file-url","tags":[]}],"exploitRefs":[{"url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-356g-m7rx-7pm3","tags":[]}],"hasPoc":true,"ai":null}
