CVE-2026-97667
MEDIUM 5.1Sonatype Nexus Repository 3 allows a user account that holds the edit permission on a hosted R repository to store script content in the metadata of an uploaded R package. The script runs in the browser of a user who opens the details of that package in the Browse user interface, with the permissions of the viewing user. In this description, a user account means an account that has supplied valid credentials. The anonymous user, if enabled, is also a user account and can hold this permission if an administrator grants it.
