CVE-2026-17594: Sonatype Nexus Repository Manager

Medium severity, CVSS 4.9. EPSS: 0.7% chance of exploitation in the next 30 days.

Nexus Repository 3 CE/Pro versions 3.0.0 through 3.94.x contain an incorrect authorization vulnerability (CWE-863) in the repository-creation user interface. An individual user account holding a delegated repository-admin privilege scoped to a specific repository format could create a repository of a different, unauthorized format, because authorization was checked against one request field while a separate, attacker-controlled field determined the repository format actually created. This does not affect the anonymous user, which cannot hold this privilege by default. Fixed in version 3.95.0.

Affected products

• Sonatype Nexus Repository Manager: from 3.0.0, before 3.95.0 (fixed in 3.95.0)
