CVE-2019-13344: Crudlab Wp Like Button

Medium severity, CVSS 5.3. EPSS: 45.1% chance of exploitation in the next 30 days.

An authentication bypass vulnerability in the CRUDLab WP Like Button plugin through 1.6.0 for WordPress allows unauthenticated attackers to change settings. The contains() function in wp_like_button.php did not check if the current request is made by an authorized user, thus allowing any unauthenticated user to successfully update settings, as demonstrated by the wp-admin/admin.php?page=facebook-like-button each_page_url or code_snippet parameter.

Affected products

• Crudlab Wp Like Button: up to and including 1.6.0
