A severe security issue has been uncovered in the widely-used Motors WordPress theme, placing around 22,000 websites in serious jeopardy.
Security experts have pinpointed a privilege escalation weakness that lets attackers bypass authentication, gaining control of administrative accounts and threatening the integrity of the entire site.
This flaw, designated CVE-2025-4322, has been assigned a high-risk CVSS score of 9.8 and impacts all versions of the Motors theme up to and including version 5.6.67.
Critical Weakness in Password Recovery – CVE-2025-4322
The vulnerability arises from inadequate validation in the password reset process within the Motors theme. A detailed Wordfence report reveals that the issue resides in the password-recovery.php template file, where password changes are executed without the necessary authentication safeguards.
The core problem with the vulnerability is the lack of validation to prevent password changes when the hash is missing.
Although there is a validation check to ensure the hash_check parameter is not empty, attackers can exploit this by providing an invalid UTF-8 character. This character is then stripped by the esc_attr() function.
This process happens after the initial check (!empty($_GET[‘hash_check’])) but before the password comparison, allowing unauthorized password resets.
This issue was discovered by security researcher Friderika Baranyai, also known as “Foxyyy,” who responsibly reported it via the Wordfence Bug Bounty Program and received a reward of over $1,000 for her discovery.
Through this vulnerability, an unauthenticated attacker can reset the password for any user on the site, including administrators. With administrative access, attackers could:
- Install malicious themes or plugins containing backdoors.
- Alter website content to redirect visitors to harmful sites.
- Inject malware or spam into the site’s content.
- Steal sensitive data stored within the WordPress system.
This vulnerability is part of a troubling trend in WordPress security, as highlighted in Wordfence’s 2024 Annual WordPress Security Report, which revealed a 68% rise in disclosed vulnerabilities over the past year.

Mitigation
Owners of sites using the Motors theme should upgrade to version 5.6.68 or later without delay, as this release includes a critical patch from StylemixThemes, made available on May 14, 2025.
For those unable to immediately update, the following protective measures are available:
- Wordfence Premium, Care, and Response subscribers received a firewall rule to mitigate the vulnerability on May 6, 2025.

- Administrators may want to temporarily deactivate the affected theme until they can apply the necessary update.
This incident highlights the critical need for regularly updating themes and plugins in WordPress environments. It also emphasizes the value of having multiple layers of security, such as Wordfence, which can identify and block threats even before official patches are rolled out.
