Name of the Vulnerable Software and Affected Versions Sonatype Nexus Repository 3 (affected versions not specified)
Description Two blobstore group management REST API endpoints fail to correctly enforce authorization checks. A user possessing only the nexus:blobstores:create permission can invoke these endpoints to convert an existing blobstore into a group blobstore, an action that normally requires the nexus:blobstores:update permission. This allows for the unauthorized modification of blobstore configurations without administrator approval. The nexus:blobstores:create permission is a named permission that must be explicitly granted by an administrator and is not assigned by default.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
