CVE-2020-8658

CWE-352Published: February 6, 2020· Updated: Jun 17, 2026

8.8
CVSS v3.1

Official Description

The BestWebSoft Htaccess plugin through 1.8.1 for WordPress allows wp-admin/admin.php?page=htaccess.php&action=htaccess_editor CSRF. The flag htccss_nonce_name passes the nonce to WordPress but the plugin does not validate it correctly, resulting in a wrong implementation of anti-CSRF protection. In this way, an attacker is able to direct the victim to a malicious web page that modifies the .htaccess file, and takes control of the website.

Technical Analysis

CVE-2020-8658 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.
