# Sonatype Nexus Repository 3: read-only user can retrieve APT/YUM signing passphrase

Sonatype Nexus Repository 3 returns the signing passphrase of an APT or YUM repository through an internal REST endpoint. A user holding only the read privilege for repository administration can obtain that passphrase, which lets them sign packages as the repository.

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

## How to check

Affected range unknown. Check whether your Nexus Repository 3 instance hosts APT or YUM repositories with a signing key and passphrase configured, and which accounts (including anonymous, if enabled) hold the read privilege for repository administration. Compare your version with the Sonatype advisory once published.
