Security Summary
CVE-2025-26566 is an Improper Neutralization of Input During Web Page Generation vulnerability, enabling Reflected Cross-Site Scripting (XSS) as classified under CWE-79. It affects the In Stock Mailer for WooCommerce WordPress plugin (in-stock-mailer-for-woocommerce) in all versions up to and including 2.1.1. The vulnerability 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), indicating high severity due to its network accessibility, low attack complexity, and lack of required privileges.
Attackers can exploit this vulnerability remotely without authentication by crafting malicious inputs or links that, when interacted with by a user (such as clicking a link), reflect and execute arbitrary JavaScript in the victim's browser context. This requires user interaction but changes scope, potentially allowing limited impacts like theft of session cookies, keystroke logging, or minor page modifications within the plugin's affected pages.
