CVE-2026-2420: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in lotekmedia LotekMedia Popup Form
The LotekMedia Popup Form plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin settings in all versions up to, and including, 1.0.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the frontend of the site where the popup is displayed.
AI Analysis
Technical Summary
CVE-2026-2420 is a stored cross-site scripting vulnerability (CWE-79) in the LotekMedia Popup Form WordPress plugin affecting all versions up to 1.0.6. The issue arises from improper neutralization of input during web page generation, specifically in the plugin settings, allowing authenticated administrators to inject arbitrary scripts that execute in the context of users visiting the frontend pages where the popup appears. This vulnerability requires high privileges (administrator) and does not require user interaction beyond visiting the affected page.
Potential Impact
An attacker with administrator-level access can inject malicious scripts that execute in the browsers of users viewing the affected popup, potentially leading to session hijacking, defacement, or other script-based attacks. The impact is limited by the requirement for administrator privileges and the lack of user interaction needed. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix is indicated, administrators should restrict plugin access to trusted users only and consider disabling or removing the plugin until a fix is available. Monitor vendor channels for updates regarding a patch or official remediation.
