CVE-2025-62018 is a missing authorization vulnerability identified in the hogash Kallyas product, specifically affecting versions up to and including 4.22.0. The flaw arises due to insufficient enforcement of authorization checks on certain functionality within the Kallyas system, allowing unauthenticated remote attackers to access resources or perform actions that should be restricted. The vulnerability is remotely exploitable over the network without requiring any privileges or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The impact is limited to confidentiality loss, with no direct effects on integrity or availability. This suggests that sensitive information could be exposed to unauthorized parties, but the system’s data and operations remain intact. No known public exploits have been reported to date, and no patches or mitigations have been linked in the provided data. The vulnerability was reserved in early October 2025 and published in November 2025, reflecting a recent discovery. Given Kallyas is a theme or plugin commonly used in WordPress environments, the vulnerability likely affects websites relying on this component for content management or presentation layers. The absence of detailed CWE classification and patch information limits deeper technical insight, but the core issue is a failure to verify user permissions before granting access to certain functions or data.

For European organizations, the primary impact of CVE-2025-62018 is unauthorized disclosure of potentially sensitive information hosted or managed via the Kallyas product. This could include business-sensitive content, user data, or configuration details that attackers might leverage for further attacks or reconnaissance. While the vulnerability does not allow modification or disruption of services, the confidentiality breach could lead to reputational damage, compliance violations (e.g., GDPR), and increased risk of targeted phishing or social engineering attacks. Organizations in sectors with stringent data protection requirements such as finance, healthcare, and government are particularly at risk. The ease of exploitation (no authentication or user interaction required) increases the threat level, especially for publicly accessible websites. However, the medium CVSS score reflects the limited scope of impact and the absence of integrity or availability concerns.

European organizations should monitor for official patches or updates from hogash addressing CVE-2025-62018 and apply them promptly once available. In the interim, administrators should audit their Kallyas installations to identify exposed endpoints or functionality lacking authorization controls. Implementing web application firewalls (WAFs) with custom rules to restrict access to sensitive Kallyas components can reduce exposure. Conduct thorough access control reviews and ensure that sensitive data is not unnecessarily exposed via the theme or plugin. Additionally, organizations should perform regular security assessments and penetration tests focusing on authorization mechanisms within their CMS environments. Logging and monitoring access patterns to detect anomalous or unauthorized requests targeting Kallyas components can provide early warning of exploitation attempts. Finally, educating web administrators about the risks of missing authorization and enforcing the principle of least privilege in CMS configurations will help mitigate similar vulnerabilities.
