A critical security vulnerability discovered in the popular Motors WordPress theme has exposed approximately 22,000 websites to significant risk.
Security researchers have identified a privilege escalation vulnerability that allows unauthenticated attackers to take over administrative accounts, potentially compromising the entire website.
This vulnerability (CVE-2025-4322) carries a critical CVSS score of 9.8 and affects all versions of the Motors theme up to and including 5.6.67.
Critical Password Reset Vulnerability – CVE-2025-4322
The security flaw stems from insufficient validation in the password recovery functionality of the Motors theme.
According to the Wordfence security report, the vulnerability exists in the password-recovery.php template file, which handles password updates without proper authentication checks:
The critical issue is that the function doesn’t include checks to prevent password updates when the hash is empty.
While there is a check to ensure the hash_check parameter is not empty, attackers can bypass this by supplying an invalid UTF-8 character that gets stripped through the esc_attr() function.
This occurs after the !empty($_GET[‘hash_check’]) check but before the comparison, allowing attackers to reset passwords without authorization.
Security researcher Friderika Baranyai (known as “Foxyyy”) discovered and responsibly reported this vulnerability through the Wordfence Bug Bounty Program, earning a bounty of over $1,000 for the finding.
An unauthenticated attacker can exploit this vulnerability to change the password of any user on the affected site, including administrators. Once administrative access is gained, attackers can:
This vulnerability follows a concerning trend in WordPress security, as Wordfence’s 2024 Annual WordPress Security Report highlighted a 68% increase in disclosed vulnerabilities compared to 2023.
