What is CVE-2026-1073?

The Purchase Button For Affiliate Link plugin for WordPress exhibits a Cross-Site Request Forgery vulnerability in all versions up to and including 1.0.2. This vulnerability arises from the absence of nonce validation in the settings page form handler, specifically located in 'inc/purchase-btn-options-page.php'. Consequently, this flaw allows unauthenticated attackers to alter plugin settings by persuading a site administrator to execute a specific action, such as clicking on a malicious link, thus compromising the security of the WordPress site.
