CVE-2026-90575

Name of the Vulnerable Software and Affected Versions PHPGurukul Small CRM version 4.0

Description An issue exists in the Login Success Handler component within the /crm/login.php file. The unserialize() function fails to properly handle the geopluginURL argument, leading to deserialization. This allows a remote attacker to initiate an attack, although the complexity is high and exploitability is considered difficult.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability. As a temporary mitigation, restrict access to the /crm/login.php endpoint or avoid using the geopluginURL argument.
