{"id":"CVE-2026-100532","published":"2026-09-26T03:16:58.660","lastModified":"2026-09-30T01:16:33.117","description":"@openclaw/whatsapp (npm) before 2026.8.1 exposes the WhatsApp login tool through the generic channel-tool path without preserving the originating sender's owner status, so the owner-only tool boundary is not enforced. An admitted non-owner sender able to steer the tool can request a forced login and receive a new QR code for a configured account, disconnecting the Gateway's WhatsApp account and causing loss of availability; full account relinking additionally requires the attacker to scan the returned QR code with another phone. The issue affects the owner-only tool boundary rather than WhatsApp transport authentication. Fixed in 2026.8.1.","cvssScore":8.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","cwes":["CWE-862"],"vendors":[],"products":[],"references":[{"url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-9m4p-cqp4-jppq","tags":[]},{"url":"https://www.vulncheck.com/advisories/openclaw-whatsapp-before-2026.8.1-authentication-bypass","tags":[]}],"exploitRefs":[{"url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-9m4p-cqp4-jppq","tags":[]}],"hasPoc":true,"ai":null}
