This vulnerability in Miguel Sirvent's Magic Embeds plugin (up to version 3.1.2) allows stored XSS due to improper input neutralization in the wp-embed-facebook feature. An attacker with low privileges can inject malicious scripts that execute when a user interacts with the affected content. The vulnerability has a CVSS 3.1 base score of 6.5, reflecting network attack vector, low attack complexity, low privileges required, user interaction needed, and impacts on confidentiality, integrity, and availability at a low level. No known exploits in the wild or patches have been reported as of the publication date.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of the victim's browser, potentially leading to data disclosure, session hijacking, or other impacts on confidentiality, integrity, and availability. The attack requires user interaction and low privileges, limiting but not eliminating risk. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
