CVE-2025-62017 is a missing authorization vulnerability identified in the hogash Kallyas WordPress theme, affecting versions up to and including 4.22.0. This vulnerability arises because the theme fails to properly verify whether a user has the necessary permissions before allowing access to certain functionality or data. As a result, an attacker with low-level privileges (PR:L) can perform unauthorized actions or access restricted information, impacting confidentiality and integrity. The CVSS 3.1 base score of 5.4 reflects a medium severity, with an attack vector of network (AV:N), low attack complexity (AC:L), and no user interaction required (UI:N). The scope remains unchanged (S:U), meaning the vulnerability affects only the vulnerable component. There are no known exploits in the wild at this time, and no official patches have been released. The vulnerability is particularly concerning for websites using the Kallyas theme, which is popular among WordPress users for e-commerce and corporate sites. Exploitation could lead to data leakage or unauthorized modifications, potentially undermining trust and compliance with data protection regulations. The lack of patches necessitates immediate mitigation through access control reviews and monitoring.

For European organizations, this vulnerability poses a risk primarily to the confidentiality and integrity of data managed through websites using the Kallyas theme. Unauthorized access could expose sensitive customer information or allow unauthorized content changes, which may lead to reputational damage, regulatory non-compliance (e.g., GDPR), and potential financial losses. E-commerce sites are particularly vulnerable to fraud or data theft. The medium severity score indicates a moderate risk, but the ease of exploitation without user interaction and only low privileges increases the threat level. Organizations relying on Kallyas for critical web infrastructure should consider the vulnerability a priority. The absence of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits once the vulnerability becomes widely known.

European organizations should immediately audit user roles and permissions within their WordPress installations to ensure that only trusted users have low-level privileges that could be exploited. Implement strict access controls and consider temporarily disabling or restricting features associated with the Kallyas theme that may be vulnerable. Monitor web server logs and WordPress activity for unusual access patterns or unauthorized changes. Employ web application firewalls (WAFs) with custom rules to block suspicious requests targeting the theme. Stay informed about vendor announcements and apply patches promptly once released. Additionally, consider isolating the affected web applications within segmented network zones to limit potential lateral movement. Regular backups and incident response plans should be updated to address potential exploitation scenarios.
