Gogs is an open source self-hosted Git service. Prior to version 0.14.2, overwritable LFS object across different repos leads to supply-chain attack, all LFS objects are vulnerable to be maliciously overwritten by malicious attackers. This issue has been patched in version 0.14.2.

Gogs is an open source self-hosted Git service. In versions 0.13.4 and below, the DeleteComment API does not verify that the comment belongs to the repository specified in the URL. This allows a repository administrator to delete comments from any other repository by supplying arbitrary comment IDs, bypassing authorization controls. The DeleteComment function retrieves a comment by ID without verifying repository ownership and the Database function DeleteCommentByID performs no repository validation. This issue has been fixed in version 0.14.0.

Gogs is an open source self-hosted Git service. Versions 0.13.4 and below expose unauthenticated file upload endpoints by default. When the global RequireSigninView setting is disabled (default), any remote user can upload arbitrary files to the server via /releases/attachments and /issues/attachments. This enables the instance to be abused as a public file host, potentially leading to disk exhaustion, content hosting, or delivery of malware. CSRF tokens do not mitigate this attack due to same-origin cookie issuance. This issue has been fixed in version 0.14.1.

Gogs is an open source self-hosted Git service. In version 0.13.3 and prior, an authenticated user can cause a DOS attack. If one of the repo files is deleted before synchronization, it will cause the application to crash. This issue has been patched in versions 0.13.4 and 0.14.0+dev.

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.

Gogs is an open source self-hosted Git service. In version 0.13.3 and prior, the endpoint "PUT /repos/:owner/:repo/contents/*" does not require write permissions and allows access with read permission only via repoAssignment(). After passing the permission check, PutContents() invokes UpdateRepoFile(), which results in commit creation and the execution of git push. As a result, a token with read-only permission can be used to modify repository contents. This issue has been patched in versions 0.13.4 and 0.14.0+dev.

routes/api/v1/api.go in Gogs 0.11.86 lacks permission checks for routes: deploy keys, collaborators, and hooks.

Missing Authorization in GitHub repository gogs/gogs prior to 0.12.5.

This vulnerability exists in the Shilpi Net Back Office due to improper access controls on certain API endpoints. An authenticated remote attacker could exploit this vulnerability by manipulating a parameter dfclientid through API request URLs which could lead to unauthorized access to sensitive information belonging to other users.

This vulnerability exists in the Wave 2.0 due to improper authorization checks on certain API endpoints. An authenticated remote attacker could exploit this vulnerability by manipulating API input parameters to gain unauthorized access and perform malicious activities on other user accounts.
