CVE-2025-7058 is a stored Cross-Site Scripting (XSS) vulnerability classified under CWE-79, found in the Kingcabs WordPress theme developed by sparklewpthemes. The vulnerability arises from improper neutralization of input during web page generation, specifically via the 'progressbarLayout' parameter. All versions up to and including 1.1.9 are affected due to insufficient input sanitization and lack of proper output escaping. An attacker with at least Contributor-level privileges on a WordPress site can inject arbitrary JavaScript code into pages by manipulating this parameter. Because the malicious script is stored persistently, it executes every time a user accesses the infected page, potentially allowing session hijacking, privilege escalation, or unauthorized actions within the context of the victim’s browser session. The CVSS v3.1 base score is 6.4, indicating medium severity, with an attack vector of network, low attack complexity, requiring privileges (PR:L), no user interaction, and a scope change (S:C). The impact affects confidentiality and integrity but not availability. No patches or public exploits have been reported as of the publication date (December 13, 2025). The vulnerability is particularly concerning in multi-user WordPress environments where contributors or editors have access, as it allows them to compromise other users, including administrators. The lack of output escaping and input validation in the theme’s code is the root cause, highlighting the need for secure coding practices in theme development.

For European organizations, the impact of CVE-2025-7058 can be significant in environments where the Kingcabs theme is deployed on WordPress sites, especially those with multiple authenticated users. Exploitation could lead to unauthorized disclosure of sensitive information (confidentiality impact) and unauthorized modification of content or user actions (integrity impact). This can result in compromised user accounts, defacement, or further pivoting within the network if administrative accounts are targeted. Although availability is not directly affected, the reputational damage and potential data breaches could have regulatory consequences under GDPR. Organizations relying on WordPress for public-facing websites, intranets, or customer portals are at risk, particularly if they allow Contributor-level access to external users or contractors. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once the vulnerability is widely known.

1. Immediately update the Kingcabs theme to a patched version once available from the vendor. If no patch is currently available, consider temporarily disabling or replacing the theme. 2. Restrict Contributor-level and higher privileges to trusted users only, minimizing the attack surface. 3. Implement Web Application Firewall (WAF) rules to detect and block suspicious input patterns targeting the 'progressbarLayout' parameter. 4. Conduct a thorough audit of all user-generated content and pages for injected scripts, removing any malicious code. 5. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts on affected sites. 6. Educate site administrators and users about the risks of XSS and the importance of least privilege principles. 7. Monitor logs for unusual activity related to page edits or script injections. 8. Consider deploying runtime application self-protection (RASP) solutions to detect and block exploitation attempts in real-time.
