Sonatype Nexus Repository Manager (Self-Hosted) 3.50.0

Sonatype Nexus Repository 3 allows a user that holds the role create or role update permission to grant roles and privileges that the account does not hold. This can give the user more access than intended, up to full administrative access.

Sonatype Nexus Repository 3 allows an unauthenticated remote attacker to supply attacker-controlled input to a Java class loading call through an ExtDirect endpoint. This allows the attacker to learn whether specific classes are present in the application. The issue does not by itself allow code execution.

Sonatype Nexus Repository 3 allows a user account that holds the edit permission on a hosted R repository to store script content in the metadata of an uploaded R package. The script runs in the browser of a user who opens the details of that package in the Browse user interface, with the permissions of the viewing user. In this description, a user account means an account that has supplied valid credentials. The anonymous user, if enabled, is also a user account and can hold this permission if an administrator grants it.

Nexus Repository 3 contained a privilege escalation vulnerability in the REST privileges API.
