Authenticated information disclosure via undisclosed endpoint flaw
Published Jul 27, 2026 · Updated Jul 27, 2026
Information disclosure in an endpoint in HCL Connections 8.0 allows remote authenticated users to obtain sensitive information. HCL has not published the endpoint, the exposed data, or the incorrect operation that makes the response accessible. Exploitation requires low-privileged authentication and user interaction, and the reported consequence is limited to confidentiality loss.
