Glexia's Take · Automated analysis
CWE-525: Use of Web Browser Cache Containing Sensitive Information
Use of Web Browser Cache Containing Sensitive Information represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
Executive Impact
- Confidentiality: Read Application Data: Browsers often store information in a client-side cache, which can leave behind sensitive information for other users to find and exploit, such as passwords or credit card numbers. The locations at most risk include public terminals, such as those in libraries and Internet cafes.
Developer Pattern
CWE-525 is the kind of defect developers can usually prevent with explicit validation, safer framework defaults, and tests that exercise hostile input or unsafe state transitions.
Automation confidence
high confidence from CWE-525, 4.20.

Official CWE Definition
CWE-525: Use of Web Browser Cache Containing Sensitive Information
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.
Developer And Remediation Guidance
How teams prevent and detect this weakness
Causes
- Missing validation
- Unsafe defaults
- Insufficient authorization or memory-safety invariant
Remediation
- Architecture and Design: Protect information stored in cache.
- 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.
- Architecture and Design: Do not store unnecessarily sensitive information in the cache.
- Architecture and Design: Consider using encryption in the cache.
Detection
- Code review
- SAST
- DAST
- Focused regression tests
