CVE-2026-25242 Crítica · 9.8 CWE-862 19/02/2026

Gogs allows unauthenticated file uploads

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.

CVE-2026-25232 Alta · 8.8 CWE-863 19/02/2026

Gogs has a Protected Branch Deletion Bypass in Web Interface

Gogs is an open source self-hosted Git service. Versions 0.13.4 and below have an access control bypass vulnerability which allows any repository collaborator with Write permissions to delete protected branches (including the default branch) by sending a direct POST request, completely bypassing the branch protection mechanism. This vulnerability in the DeleteBranchPost function eenables privilege escalation from Write to Admin level, allowing low-privilege users to perform dangerous operations that should be restricted to administrators only. Although Git Hook layer correctly prevents protected branch deletion via SSH push, the web interface deletion operation does not trigger Git Hooks, resulting in complete bypass of protection mechanisms. In oder to exploit this vulnerability, attackers must have write permissions to the target repository, protected branches configured to the target repository and access to the Gogs web interface. This issue has been fixed in version 0.14.1.

CVE-2026-25229 Média · 6.5 CWE-284 19/02/2026

Gogs Authorization Bypass Allows Cross-Repository Label Modification

Gogs is an open source self-hosted Git service. Versions 0.13.4 and below have a broken access control vulnerability which allows authenticated users with write access to any repository to modify labels belonging to other repositories. The UpdateLabel function in the Web UI (internal/route/repo/issue.go) fails to verify that the label being modified belongs to the repository specified in the URL path, enabling cross-repository label tampering attacks. The vulnerability exists in the Web UI's label update endpoint POST /:username/:reponame/labels/edit. The handler function UpdateLabel uses an incorrect database query function that bypasses repository ownership validation. This issue has been fixed in version 0.14.1.

CVE-2026-25120 Baixa · 2.7 CWE-639 19/02/2026

Gogs Allows Cross-Repository Comment Deletion via DeleteComment

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.

CVE-2026-24135 Alta · 8.1 CWE-22 06/02/2026

Gogs vulnerable to arbitrary file deletion via path traversal in wiki page update

Gogs is an open source self-hosted Git service. In version 0.13.3 and prior, a path traversal vulnerability exists in the updateWikiPage function of Gogs. The vulnerability allows an authenticated user with write access to a repository's wiki to delete arbitrary files on the server by manipulating the old_title parameter in the wiki editing form. This issue has been patched in versions 0.13.4 and 0.14.0+dev.

CVE-2026-23633 Média · 6.5 CWE-22 06/02/2026

Gogs has arbitrary file read/write via path traversal in Git hook editing

Gogs is an open source self-hosted Git service. In version 0.13.3 and prior, there is an arbitrary file read/write via path traversal in Git hook editing. This issue has been patched in versions 0.13.4 and 0.14.0+dev.

CVE-2026-23632 Média · 6.5 CWE-862 06/02/2026

Gogs user can update repository content with read-only permission

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.

CVE-2026-22592 Média · 6.5 CWE-862 06/02/2026

Gogs is Vulnerable to Denial of Service

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.

CVE-2025-64175 Alta · 8.8 CWE-287 06/02/2026

Gogs Vulnerable to 2FA Bypass via Recovery Code

Gogs is an open source self-hosted Git service. In version 0.13.3 and prior, Gogs’ 2FA recovery code validation does not scope codes by user, enabling cross-account bypass. If an attacker knows a victim’s username and password, they can use any unused recovery code (e.g., from their own account) to bypass the victim’s 2FA. This enables full account takeover and renders 2FA ineffective in all environments where it's enabled.. This issue has been patched in versions 0.13.4 and 0.14.0+dev.
