What is CVE-2025-52892?

EspoCRM is a versatile web application featuring a single-page application frontend and a REST API backend built in PHP. In versions prior to 9.1.7, a potential vulnerability arises when users access EspoCRM with a URL that contains double slashes (e.g., https://domain//#Admin). If the webserver fails to strip these double slashes, it can lead to a corrupted cache in the Slim router, rendering the application unusable until a full rebuild is performed. This issue highlights the importance of proper URL handling in web applications.
