CVE-2026-10748Network attack vector

Authenticated command execution via crafted license deserialization

Published Jun 16, 2026 · Updated Jun 16, 2026

Deserialization of untrusted data in Sonatype Nexus Repository 3 before 3.92.0 allows remote authenticated users to execute OS commands. The license installation functionality deserializes a specially crafted uploaded license file in a way that invokes arbitrary commands as the Nexus process user. Access requires the nx-licensing-create privilege, which is assigned to administrators by default but can be delegated; successful exploitation compromises the server.
