AJS Footnotes <= 1.0 - Unauthenticated Stored Cross-Site Scripting

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVE CVE-2025-15378
CVSS High (7.2)
Publicly Published January 13, 2026
Last Updated January 14, 2026
Researcher 0x34rth
Description

The AJS Footnotes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'note_list_class' and 'popup_display_effect_in' parameters in all versions up to, and including, 1.0 due to missing authorization and nonce verification on settings save, as well as insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to update plugin settings and inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
