CVE-2026-52799 Details
Description
Gogs is an open source self-hosted Git service. Prior to 0.14.3, GET /attachments/:uuid returns the raw attachment file without verifying whether the requester has view permission for the associated Issue/Comment/Release or the repository. In a test environment with REQUIRE_SIGNIN_VIEW = false, we confirmed that an unauthenticated user can download attachments belonging to a private repository. This vulnerability is fixed in 0.14.3.
A vulnerability in Gogs prior to version 0.14.3 allows unauthenticated users to download attachments from private repositories. The issue arises because the attachment download endpoint, `GET /attachments/:uuid`, does not verify whether the requester has the appropriate permissions to view the associated Issue, Comment, Release, or the repository itself. In environments where `REQUIRE_SIGNIN_VIEW` is set to false, this flaw can be exploited to access private files. Even with `REQUIRE_SIGNIN_VIEW` enabled, the vulnerability could still be exploited by logged-in users who lack permission for the target repository, as the endpoint does not check repository-level access.
Users can upgrade to Gogs version 0.14.3, where this vulnerability has been patched.
