Deeper analysis

CVE-2026-25452 is an Improper Neutralization of Input During Web Page Generation vulnerability, commonly known as Stored Cross-Site Scripting (XSS) and classified under CWE-79, affecting the Remoji WordPress plugin. This issue impacts all versions of Remoji from n/a through 2.2 inclusive. The vulnerability was published on 2026-03-25 and 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).

The attack requires no privileges and can be initiated over the network with low complexity, though it demands user interaction for successful exploitation. An attacker can store malicious scripts via the plugin, which then execute in the context of other users viewing affected pages, potentially leading to limited impacts on confidentiality, integrity, and availability due to the changed scope.

Patchstack has issued an advisory documenting the Stored XSS vulnerability in the Remoji WordPress plugin version 2.2, available at https://patchstack.com/database/Wordpress/Plugin/remoji/vulnerability/wordpress-remoji-plugin-2-2-cross-site-scripting-xss-vulnerability?_s_id=cve.
