Security Summary

CVE-2025-25083 is an Improper Neutralization of Input During Web Page Generation vulnerability, classified as Stored Cross-site Scripting (XSS) under CWE-79, in the EP4 More Embeds WordPress plugin by Dave Lavoie. The issue affects the plugin from its initial release through version 1.0.0. Published on 2025-03-03, it carries a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L).

Attackers can exploit this over the network with low complexity and no required privileges, though it demands user interaction. Successful exploitation changes the security scope, enabling low-impact violations of confidentiality, integrity, and availability. A remote attacker could inject and store malicious scripts through the plugin, which then execute in the browser context of authenticated users viewing affected pages.
