Vulnerability

Description

A caching vulnerability occurs when sensitive information is stored and retrieved by caching components such as proxy servers, potentially leaking user data or enabling session hijacking attacks. This issue arises in environments with shared caching servers, commonly found in corporate or educational networks.

Recommendation

To mitigate this risk, ensure that responses do not contain sensitive information. If necessary, set HTTP response headers like Cache-Control: no-cache, no-store, must-revalidate, private and Pragma: no-cache to prevent caching and retrieval of the content without validation.
