Short explanation
An issue in GitLab CE/EE affects versions before 19.2.8, 19.3 before 19.3.5, and 19.4 before 19.4.2, allowing cached responses for raw repository files to be poisoned under certain conditions due to improper repository reference validation.
It poses a high risk as it can allow users to manipulate CI/CD pipelines and potentially expose protected environment variables through cache poisoning.
What should be done?
- Follow vendor advisories for updates
- Upgrade GitLab CE/EE to unaffected versions
- Review repository reference validation controls
Chain of evidence and sources
GitLab CE ve EE sürümlerinde 19.2.8, 19.3.5 ve 19.4.2 öncesi sürümler zafiyetten etkilenmektedir.
Zafiyet, ham depo dosyaları için önbelleğe alınmış yanıtların zehirlenmesine neden olabilir.
Bu durum CI/CD hatlarının özel içerik çalıştırmasına ve korumalı ortam değişkenlerinin açığa çıkmasına yol açabilir.
