CVE-2023-45696

Sensitive data disclosure via browser autocomplete

Published Feb 10, 2024 · Updated Jun 3, 2025

Information disclosure in HCL Sametime 11.5 through 12.0.1 FP1 allows physically proximate attackers to read browser-stored chat data. The Legacy web chat client renders sensitive input fields with autocomplete enabled, so the browser retains user-entered values in its local form cache. Exploitation requires user interaction and physical access to the affected browser profile, and the reported consequence is limited to disclosure of retained data.
