  • Sep 24, 2026OpenWA is a free, open source, self-hosted WhatsApp API gateway.CVE-2026-91161 · Other software · rmyndharis · reported by GitHubMedium 6.4

    OpenWA is a free, open source, self-hosted WhatsApp API gateway. Prior to 0.23.5, the GET /api/sessions/{sessionId}/groups/{groupId}/invite-code endpoint and the GroupGetInviteCode MCP tool have no OPERATOR role requirement, allowing a valid VIEWER key scoped to a session to retrieve an active group invite code. The invite code is a transferable WhatsApp bearer capability, so an external account can join a group administered by the session without an OpenWA credential, gain read and post access to the group, and retain membership after the VIEWER key is revoked. Affected deployments are those that issue VIEWER keys to parties who should not be able to add accounts to administered groups; OPERATOR and ADMIN access is intended. This issue is fixed in version 0.23.5.

  • Sep 24, 2026OpenWA is a free, open source, self-hosted WhatsApp API gateway.CVE-2026-91160 · Other software · rmyndharis · reported by GitHubHigh 8.2

    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.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
