AI-suggested
Upgrade Nexus Repository 3 to version 3.95.0 or later, where this SSRF vulnerability is fixed. Since the vulnerability requires the nexus:settings:update permission, restrict this permission to trusted users only as an additional mitigation. Patch status is confirmed fixed in 3.95.0.
Description
Nexus Repository 3 contains a Server-Side Request Forgery (SSRF) vulnerability in the email configuration verification feature. A user holding the nexus:settings:update permission could submit arbitrary host and port values to the email test/verification endpoint, causing the server to attempt outbound network connections to internal or otherwise restricted network addresses. Differences in the server's response could be used to infer whether internal hosts and ports are reachable. This issue affects Nexus Repository 3 CE/Pro versions up to and including 3.94.1, and is fixed in version 3.95.0.
