CVE-2026-91773 Details
Description
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.
A vulnerability in Soft Serve versions 0.7.1 through 0.11.6 allows authenticated users with write access to any repository to access Git LFS lock metadata from private repositories they cannot otherwise reach. The issue arises because lock queries are not properly scoped by repository, enabling users to enumerate lock IDs globally and retrieve sensitive information such as locked file paths, usernames, and lock timestamps from inaccessible repositories.
Users are advised to upgrade to Soft Serve version 0.12.0 or later, where this vulnerability has been patched. Instructions for upgrading can be found on the Soft Serve GitHub repository.
