Reflected Cross-Site Scripting in SponsorMe WordPress Plugin

Publication date: 2026-05-20

Last updated on: 2026-05-20

Assigner: Wordfence

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 β€” a form action attribute and an anchor href attribute β€” both of which can be exploited by appending a crafted payload to the wp-admin/admin.php URL path.

Can you explain this vulnerability to me?

The SponsorMe plugin for WordPress has a Reflected Cross-Site Scripting (XSS) vulnerability in all versions up to and including 0.5.2. This occurs because the plugin does not properly sanitize or escape input from the PHP_SELF parameter. An attacker can craft a malicious URL that includes a script payload in the PHP_SELF value, which is then reflected in two places on the page: a form's action attribute and an anchor's href attribute. If a user clicks on such a crafted link, the injected script executes in their browser.


How can this vulnerability impact me? :

This vulnerability allows unauthenticated attackers to inject and execute arbitrary scripts in the context of a user's browser session. This can lead to various impacts such as theft of user credentials, session hijacking, or performing actions on behalf of the user without their consent. Since the attack requires tricking a user into clicking a malicious link, it relies on social engineering but can compromise user data and site integrity.
