What is CVE-2025-69581?

A vulnerability has been identified in Chamillo LMS version 1.11.2, where the /personal_data endpoint improperly manages sensitive user information due to missing cache-control directives. As a result, even after a user logs out, their personal data can still be accessed by using the browser's back button, permitting unauthorized individuals on the same device to retrieve confidential information. This flaw significantly heightens the risk of user profiling, impersonation, and targeted attacks, thereby posing serious concerns regarding privacy and data security.
