SponsorMe # CVE-2026-8626

CVE, Research URL

CVE-2026-8626

Application

SponsorMe

Date
May 20, 2026
Research Description
The SponsorMe plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via PHP_SELF Parameter in all versions up to, and including, 0.5.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. The PHP_SELF value is reflected in two separate locations within the vulnerable function — a form action attribute and an anchor href attribute — both of which can be exploited by appending a crafted payload to the wp-admin/admin.php URL path.
Affected versions
max 0.5.2.
Status
vulnerable
