CVE-2026-105267— Gitea tag delete route deletes releases without release permission

Quick assessment

Affected
Gitea Gitea
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Gitea 用于删除标签的 Web 路由（ ）仅需代码模块的写权限即可触发，但它与发布版本（Release）删除操作共享同一个处理程序，并且未对目标是否为普通标签进行校验。因此，拥有代码写权限但不具备发布版本写权限的协作者，可能永久删除该仓库中已发布的发布版本，包括其附属文件。不过，如果发布版本所关联的标签受保护标签规则保护，则仍能阻止删除操作。

Vulnerability Title
Gitea tag delete route deletes releases without release permission
Source: CVE Program / CVE List V5
Vulnerability Description
The Gitea web route for deleting tags (`POST /{owner}/{repo}/tags/delete`) requires only write access to the Code unit, but shares its handler with release deletion and did not check that the target was a plain tag. A collaborator with Code write access and without Releases write access could permanently delete published releases of that repository, including their attachments. Protected tag rules covering the release tag still blocked the deletion.
