Official Description
HCL Connections is vulnerable to information disclosure. In a very specific user navigation scenario, this could allow a user to obtain limited information when a single piece of internal metadata is returned in the browser.
Technical Analysis
CVE-2025-52603 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
