Phpgurukul · Small Crm · 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.
