A group sender who is admitted for ordinary messages but denied by commands.allowFrom or owner command authorization can issue the /new <model> command to reset the shared group session and persist a provider and model override. This allows a command-denied group member to select a provider and model already permitted by the operator for subsequent turns in the shared group session, potentially changing provider routing, cost, data flow, or availability. It does not allow adding a new provider or host command execution. The issue is fixed in version 2026.8.1.","cvssScore":6.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","cwes":["CWE-863"],"vendors":[],"products":[],"references":[{"url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-mm7m-wcgh-8mfq","tags":[]},{"url":"https://www.vulncheck.com/advisories/openclaw-before-2026.8.1-authentication-bypass-via-session-reset","tags":[]}],"exploitRefs":[{"url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-mm7m-wcgh-8mfq","tags":[]}],"hasPoc":true,"ai":null}
