The Auto Last Youtube Video plugin by David Merinas contains a CSRF vulnerability that enables stored XSS attacks. This affects all versions up to 1.0.7. The vulnerability allows an attacker to trick an authenticated user into submitting unwanted requests, which can result in malicious scripts being stored and executed in the context of the affected application. The CVSS 3.1 vector indicates the attack can be performed remotely without privileges, requires user interaction, and impacts confidentiality, integrity, and availability to a limited extent.

Successful exploitation could allow an attacker to execute stored XSS attacks via CSRF, potentially leading to unauthorized actions performed with the victim's privileges. The impact includes limited confidentiality, integrity, and availability loss. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider disabling the plugin or limiting its use to trusted environments. Monitor vendor channels for updates and apply patches promptly once released.
