Doc Text:
A flaw was found in Sonatype Nexus Repository. This vulnerability allows an authenticated attacker with privileges to add or edit group repositories to bypass access controls, leading to information disclosure. Because the application does not verify whether an account is authorized to access an individual repository before adding it to a group repository, the attacker can add a restricted repository to a group they manage and read its contents.

Description OSIDB Bzimport 2026-11-05 22:35:53 UTC 
Sonatype Nexus Repository 3 does not check that a user account is authorized to access a repository before the repository is added as a member of a group repository. A user account that has signed in with valid credentials and holds the add or edit privilege on a group repository can add a repository that the account cannot read or browse, and then read the content of that repository through the group. The anonymous user can only do this if an administrator has explicitly granted it that privilege.
