1) Cross-site request forgery

EUVDB-ID: #VU18955

Risk: Low

CVSSv3.1: 4.2 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:N/A:L/E:P/RL:O/RC:C]

CVE-ID: N/A

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

Exploit availability: No

Description

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".

Mitigation

Install updates from vendor's website.
