What is CVE-2026-14645?

CVE-2026-14645 is a medium-severity server-side request forgery vulnerability in Sonatype Nexus Repository Manager, published on 14 Jul 2026. An attacker needs administrator access to exploit it, with no action from the victim.

Official description

Nexus Repository 3 does not validate the destination of the "Webhook: Global" capability's configured URL before making an outbound HTTP request, allowing a user holding the Capability Administration permission to cause the server to send requests to internal network locations (Server-Side Request Forgery). This permission is granted by role assignment, independent of authentication status, so an unauthenticated user could also trigger this behavior if the anonymous role has been granted the permission.
