What to know
- What it is
- When a Gitea Actions run was inserted, older runs in the same workflow-level concurrency group were cancelled without checking whether the new run still needed approval. Because fork pull request runs are inserted under the base repository, a user who can open a pull request from a fork could cancel trusted in-progres…
- Affected
- Gitea
- Fix
- Apply the vendor's security update; see the linked advisory.
- Exploitation
- No known exploitation
Story map
At a glance
Gitea: Amber, patch this week. 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 def…

Original description
When a Gitea Actions run was inserted, older runs in the same workflow-level concurrency group were cancelled without checking whether the new run still needed approval. Because fork pull request runs are inserted under the base repository, a user who can open a pull request from a fork could cancel trusted in-progress runs that share a concurrency group with `cancel-in-progress` enabled, without approval and without running any code. On self-hosted runners this can interrupt deployments and leave partial state behind.
