## Overview

Soft Serve versions 0.7.1 through 0.11.6 fail to scope Git LFS lock queries by repository, allowing authenticated users to read lock metadata from repositories they cannot access. Attackers with write access to any repository can enumerate lock IDs globally to recover locked file paths, usernames, and lock timestamps from private repositories.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
