Weakness (CWE)

CWE-525: Use of Web Browser Cache Containing Sensitive Information

Variant Incomplete

The web application does not use an appropriate caching policy that specifies the extent to which each web page and associated form fields should be cached.

How to prevent it (4 mitigations)
  1. Architecture and Design

    Protect information stored in cache.

  2. Implementation

    Use a restrictive caching policy for forms and web pages that potentially contain sensitive information, such as "no-cache" in the Cache-Control header.

  3. Architecture and Design

    Do not store unnecessarily sensitive information in the cache.

  4. Architecture and Design

    Consider using encryption in the cache.
