CVE-2026-94205— Gitea fork workflow approval bypass through maintainer-triggered events
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 Actions 在判断来自 Fork 的拉取请求（Pull Request）运行是否需要审批时，依据的是触发该事件的用户，而非拉取请求的作者。在常规问题分类（triage）过程中，由维护者触发的 活动（例如添加标签），会直接创建运行任务，而无需经过审批；然而，工作流的定义仍取自 Fork 仓库的 HEAD 分支。当启用了 Gitea Actions 且已注册匹配的运行器（runner）时，Fork 控制的工作流代码便可在基础仓库（base repository）的运行器上执行，而无需明确授权。

Vulnerability Title
Gitea fork workflow approval bypass through maintainer-triggered events
Source: CVE Program / CVE List V5
Vulnerability Description
Gitea Actions decided whether a fork pull request run needed approval based on the user who triggered the event rather than the pull request author. For `pull_request` activity triggered by a maintainer during ordinary triage, such as adding a label, the run was created without requiring approval, while the workflow definition was still taken from the fork head. Where Actions is enabled and a matching runner is registered, fork-controlled workflow code could run on the base repository's runners without an explicit approval.
