SuiteCRM: Authenticated SSRF in CalendarAccount testConnection Allows Internal Network Access and Response Disclosure

Overview

SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to 7.15.2 and 8.10.2, the CalendarAccount testConnection action passes an authenticated caller's server_url directly to curl without host, address, or scheme validation. The affected flow begins at CalendarAccount::action_testConnection and uses server_url, CalDAVProvider::makeCalDAVRequest(), and PROPFIND to carry attacker-controlled data or authorization state into the security-sensitive operation. The server sends a PROPFIND request from its network context and returns non-success response bodies, enabling internal-service access, partial response disclosure, service enumeration, and possible cloud metadata access. This issue is fixed in versions 7.15.2 and 8.10.2.
