# Sonatype Nexus Repository 3: read-only account can extract YUM repository signing key

Sonatype Nexus Repository 3 returns the private signing key of a YUM proxy or group repository to any account holding only the read privilege for that repository, per the NVD-derived description. A holder of that key can sign repository metadata as that repository. No Sonatype advisory with affected or fixed versions was found yet.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

Unknown affected range. Check whether your Nexus Repository 3 instance has YUM proxy or group repositories with a GPG signing key configured, and which accounts (including anonymous, if enabled) hold read on them. Compare your version against the Sonatype advisory once published.

## From the sources

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.
