# CVE-2026-91993

> 5.3 MEDIUM · 🧪 PoC

## Beschreibung

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.
