CVE-2026-28740 Details
Description
Gitea versions up to and including 1.26.2 allow Git LFS object reuse to authorize private source objects for users who have repository access but lack Code-unit access.
An authorization vulnerability has been identified in Gitea's Git Large File Storage (LFS) object reuse process, affecting versions through 1.26.2. This vulnerability allows users with repository access but without Code-unit access to authorize private source objects from repositories they do not fully control. The issue arises because the authorization check for source LFS objects relies on broad repository access rather than requiring specific Code-unit access. As a result, a user with non-Code access, such as Issues access, can improperly reuse LFS objects from private repositories.
Users are advised to upgrade to Gitea version 1.26.3 or later, where this vulnerability has been patched.
