{"cve":"CVE-2026-91160","nvd":{"published":"2026-09-24T17:17:09.257","modified":"2026-10-05T16:17:17.470","status":"Deferred","description":"OpenWA is a free, open source, self-hosted WhatsApp API gateway. Prior to 0.23.5, the /events WebSocket gateway delivers the session.qr event to a VIEWER API key that subscribes by event name or through either wildcard subscription form, even though GET /api/sessions/{sessionId}/qr requires the OPERATOR role. When an allowed session is waiting to be paired, the exposed QR lets the key holder link an external device to the WhatsApp account and then read and send messages outside OpenWA and its audit trail. Keys restricted through allowedSessions remain limited to those sessions, and deployments that issue only OPERATOR or ADMIN keys are not affected. This issue is fixed in version 0.23.5.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N","score":8.2},"cwes":["CWE-862"],"references":["https://github.com/rmyndharis/OpenWA/commit/acc23c3803c07f43791a92e8e48456572fd69bdc","https://github.com/rmyndharis/OpenWA/commit/b9d9ea1c57bde98b7833a5d6e482998703667ef0","https://github.com/rmyndharis/OpenWA/pull/1602","https://github.com/rmyndharis/OpenWA/releases/tag/v0.23.5","https://github.com/rmyndharis/OpenWA/security/advisories/GHSA-m427-j4h4-9qwj"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-91160","score":0.0025,"percentile":0.16146,"date":"2026-10-26"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
