CVE-2025-7058 is a stored cross-site scripting vulnerability identified in the Kingcabs WordPress theme developed by sparklewpthemes. The vulnerability exists due to improper neutralization of input during web page generation, specifically in the handling of the 'progressbarLayout' parameter. This parameter is insufficiently sanitized and escaped before being rendered on pages, allowing an authenticated attacker with Contributor-level privileges or higher to inject arbitrary JavaScript code. Because the vulnerability is stored, the malicious script persists in the website’s content and executes every time a user accesses the affected page. The vulnerability affects all versions up to and including 1.1.9 of the Kingcabs theme. The CVSS 3.1 base score is 6.4, reflecting a medium severity level, with an attack vector of network, low attack complexity, requiring privileges (Contributor or above), no user interaction, and a scope change. The impact primarily affects confidentiality and integrity, as attackers can steal session cookies, perform actions on behalf of users, or manipulate page content. There are no known public exploits at the time of disclosure, and no official patches have been linked yet. The vulnerability was reserved in July 2025 and published in December 2025. This flaw is categorized under CWE-79, which relates to cross-site scripting due to improper input validation and output encoding.

The impact of CVE-2025-7058 is significant for organizations using the Kingcabs WordPress theme, particularly those allowing Contributor-level or higher access to users. Exploitation enables attackers to inject persistent malicious scripts that execute in the context of any user viewing the compromised page. This can lead to session hijacking, unauthorized actions performed with victim user privileges, defacement, phishing, or distribution of malware. Since the vulnerability affects confidentiality and integrity but not availability, the primary risks involve data theft and unauthorized manipulation of website content or user sessions. Organizations with public-facing websites using this theme may suffer reputational damage, loss of user trust, and potential compliance issues if sensitive user data is exposed. The requirement for authenticated access limits exploitation to insiders or compromised accounts, but this does not eliminate risk, especially in environments with many contributors or weak access controls. The absence of known exploits currently provides a window for mitigation before widespread abuse occurs.

To mitigate CVE-2025-7058, organizations should immediately review user roles and permissions, restricting Contributor-level access to trusted users only. Implement strict input validation and output encoding for all user-supplied data, particularly the 'progressbarLayout' parameter, to prevent script injection. Monitor and audit content changes made by contributors for suspicious or unauthorized modifications. Apply any available updates or patches from sparklewpthemes as soon as they are released. If patches are not yet available, consider temporarily disabling or replacing the Kingcabs theme with a secure alternative. Employ Web Application Firewalls (WAFs) with custom rules to detect and block malicious payloads targeting this parameter. Educate content contributors about the risks of injecting untrusted content and enforce strong authentication mechanisms such as multi-factor authentication to reduce the risk of compromised accounts. Regularly scan websites for XSS vulnerabilities using automated tools and conduct manual code reviews focusing on input handling. Finally, maintain comprehensive backups to enable quick recovery if an attack occurs.
