• Severity: medium (CVSS 5.4 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days

• Weakness: CWE-863

Description

Soft Serve is a self-hostable Git server for the command line. Prior to version 0.11.2, an authorization bypass in the LFS lock deletion endpoint allows any authenticated user with repository write access to delete locks owned by other users by setting the force flag. The vulnerable code path processes force deletions before retrieving user context, bypassing ownership validation entirely. This issue has been patched in version 0.11.2.

Affected products

• charmbracelet soft-serve: before 0.11.2 — fixed in 0.11.2

How to fix

Upgrade to a fixed version: charmbracelet soft-serve 0.11.2. Check the vendor advisory for mitigations.
