Authenticated XSS via Angular expression injection
Published Aug 27, 2025 · Updated Aug 28, 2025
Reflected XSS in Gitblit 1.7.1 allows remote authenticated users with administrator access to execute JavaScript through a crafted request. The summary endpoint treats the r parameter as an Angular expression, allowing constructor-based payloads to execute in the rendered application context. Administrator authentication is required, and successful execution can expose session data or alter actions performed in the affected web interface.
