User-directory disclosure via missing no-cache headers
Published Apr 24, 2025 · Updated Apr 25, 2025
Sensitive-data caching in HCL Leap before 9.3.4 allows local users to read user directory information from cached responses. Responses containing user directory information omit no-cache headers, allowing a local cache to retain content that should not be stored. Exploitation requires low-privileged local access and user interaction; the reported consequence is limited to disclosure of directory data.
