Description

This security bulletin contains information about 1 vulnerability.


1) Cross-site request forgery (CVE-ID: N/A)

CWE-ID: CWE-352 - Cross-Site Request Forgery (CSRF)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear


The vulnerability allows a remote attacker to perform cross-site request forgery attacks.

The vulnerability exists due to insufficient validation of the HTTP request origin and lack of authorisation checks in the "bwpl_configure_slug()" function registered as an "admin_init" action. A remote attacker can change the plugin settings at "/wp-admin/options-permalink.php" and disable the protection.

This vulnerability leads to unauthorized option update via CSRF or unauthenticated usage of the "admin-ajax.php".


Remediation

Install update from vendor's website.
