AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability in Gitea occurs because the system does not properly verify whether a user is authorized when canceling scheduled auto-merges through the web interface. As a result, any user with read access to pull requests can cancel auto-merges that were scheduled by other users, which they should not normally be able to do.
How can this vulnerability impact me? :
The vulnerability allows users with only read access to interfere with the development workflow by canceling auto-merges scheduled by others. This can disrupt collaboration, delay code integration, and potentially cause confusion or conflicts in the codebase management process.
