Executive Summary

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.

Impact Analysis

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.
