Doc Text:
A flaw was found in Sonatype Nexus Repository. An authenticated user with read-only administrative privileges can retrieve the private signing key of a Yellowdog Updater, Modified (YUM) proxy or group repository without requiring edit permissions. This information disclosure allows an attacker to sign repository metadata as that repository, potentially enabling the spoofing or tampering of software packages.

Description OSIDB Bzimport 2026-11-05 22:03:18 UTC
Sonatype Nexus Repository 3 returns the private signing key of a YUM proxy or group repository to an account that holds only the read privilege for administering that repository. The account does not need the privilege to edit the repository. A party that holds the key can sign repository metadata as that repository.
