Summary
A vulnerability in Sonatype Nexus Repository Manager allows a remote attacker to gain unauthorized access to repository operations as a targeted user. Exploitation requires enabling a format-specific API key realm (NuGet API Key, Docker Bearer Token, or npm Bearer Token) and the targeted user having an active API key.
Risk Assessment
The risk involves potential takeover of repository operations by an attacker, leading to data theft, artifact modification, or system integrity compromise.
Recommendation
It is recommended to immediately disable unused format-specific API key realms and regularly review and rotate active user API keys.
