CVE-2026-71184

This allows execution of fork-controlled workflow code across the intended approval boundary.

HIGH 8.8EPSS 0.49%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.49%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Gitea's pull request review notifier does not attach the pull request to the Actions notification, so the fork workflow approval gate does not recognize the run as originating from a fork. Review comment and review approval or rejection events can consequently load workflow code from the fork head and run it on the base repository's runners without the required maintainer approval. This allows execution of fork-controlled workflow code across the intended approval boundary.
