CVE-2026-14645: Sonatype Nexus Repository 3 SSRF in Webhook Global capability

CVE-2026-14645 · Severity: info · CVSS 5.1 · Published 2026-07-14

Sonatype Nexus Repository 3, a platform used by organizations to manage and store software components, contains a vulnerability in its webhook configuration system. An authorized administrator (or an unauthenticated user if anonymous permissions are misconfigured) can force the server to send requests to internal network locations that should normally be inaccessible. This could allow an attacker to probe internal infrastructure or interact with private services, potentially leading to further network compromise.

Technical details

A Server-Side Request Forgery (SSRF) vulnerability exists in Sonatype Nexus Repository 3 within the 'Webhook: Global' capability. The application fails to validate the destination URL before initiating outbound HTTP requests. An attacker with 'Capability Administration' permissions can exploit this to make the server send requests to internal network resources. While this typically requires high privileges, it can be triggered by unauthenticated users if the 'anonymous' role has been granted the necessary administrative permissions. The issue is resolved in Nexus Repository version 3.94.0.
