CVE-2023-37517

Sensitive-data disclosure via missing cache-prevention headers

Published Apr 30, 2025 · Updated May 1, 2025

Sensitive-data caching in HCL Domino Leap 1.0 through 1.0.5 and 1.1 through 1.1.1 allows local users to read protected data. Affected HTTP responses omit cache-prevention headers, allowing client-side caches to retain sensitive response content after use. Exploitation requires low-privileged local access and user interaction; the consequence is limited to disclosure of cached data, with no reported modification or service interruption.
