Short explanation
An authorization flaw in Gitea allows fork workflow approval gates to be bypassed during review events, enabling code execution on base repository runners without maintainer approval.
This vulnerability enables authenticated attackers to bypass intended approval boundaries and execute untrusted workflow code on runners, posing high risks to confidentiality, integrity, and availability.
What should be done?
- Follow vendor advisories and patch recommendations
- Review the provided pull request and patch references
- Update Gitea software to secure releases
Chain of evidence and sources
Gitea çekme isteği inceleme bildiricisi, Actions bildirimine çekme isteğini eklemediği için onay kapısı çalışmanın çataldan geldiğini algılayamaz.
İnceleme yorumu, onay veya reddetme olayları çatal başlığından iş akışı kodunu yükleyerek bakımcı onayı olmadan temel havuz çalıştırıcılarında çalıştırabilir.
Etkilenen sürümler 1.20.0 ile 1.27.1 arasındadır ve CVSS temel puanı 8.8 olarak belirlenmiştir.
Show the technical text from the sources
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.
