CVE-2026-14645Network attack vector

Internal network access via unchecked webhook URL

Published Jul 14, 2026 · Updated Jul 14, 2026

SSRF in Webhook: Global in Sonatype Nexus Repository 3 before 3.94.0 allows remote authenticated users to reach internal services. The capability accepts a configured destination without validating its network location before the server issues the outbound request. Capability Administration is restricted to administrators by default, but anonymous access becomes possible if that permission is assigned to the anonymous role; requests can reach internal services, management interfaces, or cloud metadata endpoints.
