CVE-2026-14646: Sonatype Nexus Repository Manager

High severity, CVSS 7.7. EPSS: 0.3% chance of exploitation in the next 30 days.

Nexus Repository 3 did not apply its existing Server-Side Request Forgery (SSRF) protections to HTTP redirect targets returned by proxy repository upstream servers. Any user with read access to a proxy repository backed by an attacker-controlled or compromised upstream server — including an anonymous user, if anonymous access is enabled — could receive a response from an internal network address or cloud metadata endpoint as repository content, potentially exposing sensitive information such as cloud IAM credentials.

Affected products

• Sonatype Nexus Repository Manager: from 3.0.0, before 3.94.0 (fixed in 3.94.0)
