Nexus Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') Vulnerability (CVE-2026-113369)
Description
Sonatype Nexus Repository 3 allows a user account that can push manifests to a hosted OCI repository (a user account that holds the edit permission on that repository) to store script content in the artifact type field of an OCI manifest. The script runs in the browser of a user who opens the Attestations tab for the related image in the Browse user interface, with the permissions of the viewing user.
