Technical details
The Regular Labs Cache Cleaner Pro extension for Joomla (versions 1.0.0 through 9.7.6) suffers from an information disclosure vulnerability (CWE-200). Sensitive CDN credentials are leaked by being included directly in the query parameters of administrator request URLs. An attacker with access to HTTP logs, proxy logs, or browser history could extract these credentials to gain unauthorized access to the configured CDN provider. This vulnerability is triggered during normal administrative operations within the Joomla backend. Users should update to a version beyond 9.7.6 if available.
