CVE-2026-91773: Charmbracelet Soft-Serve

Medium severity, CVSS 4.3. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Charmbracelet Soft-Serve: from 0.7.1, before 0.12.0 (fixed in 0.12.0)
