## Overview

Jpom through 2.11.12 fails to validate workspace ownership when resolving repositoryId on the /build/branch-list endpoint, allowing authenticated users to access repositories from other workspaces. Attackers can submit repository identifiers from different workspaces to enumerate repository existence, determine repository type, and execute git ls-remote commands using other workspaces' stored credentials.
