GHSA-72r3-24x4-j46c: SuiteCRM: Authenticated SSRF in CalendarAccount testConnection Allows Internal Network Access and Response Disclosure

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 serverurl directly to curl without host, address, or scheme validation. The affected flow begins at CalendarAccount::actiontestConnection and uses serverurl, 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.
