Sensitive-data disclosure via missing no-cache headers

Published Apr 24, 2025 · Updated Apr 25, 2025

Sensitive-data caching in HCL Leap before 9.3.9 allows local users to read protected content from a browser cache. Affected HTTP responses omit no-cache headers, allowing the browser to retain sensitive response content after it is displayed. Exploitation requires low-privileged local access and user interaction, and the documented impact is disclosure of cached data only.
