CVE-2025-62017 identifies a Missing Authorization vulnerability in the hogash Kallyas product, affecting versions up to and including 4.22.0. This vulnerability arises from insufficient authorization checks within the application, allowing users with low-level privileges to perform actions beyond their intended permissions. The CVSS 3.1 base score is 5.4 (medium), with an attack vector of network (AV:N), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), and limited impact on confidentiality (C:L) and integrity (I:L), with no impact on availability (A:N). The vulnerability enables an authenticated attacker to potentially access or modify data they should not have access to, but does not allow for privilege escalation to administrative levels or denial of service. No public exploits or active exploitation in the wild have been reported as of the publication date. The vulnerability affects the Kallyas product, a PHP-based CMS or theme framework commonly used in website development, which is popular in various European markets. The lack of a patch link indicates that a fix may not yet be publicly available, emphasizing the need for vigilance and interim mitigations. The vulnerability was reserved in early October 2025 and published in November 2025, indicating recent discovery and disclosure.

For European organizations using hogash Kallyas, this vulnerability poses a risk of unauthorized data access or modification by authenticated users with limited privileges. This could lead to exposure of sensitive information or unauthorized changes to website content or configurations, potentially undermining data integrity and trustworthiness. While the vulnerability does not allow for denial of service or full administrative takeover, the unauthorized actions could facilitate further attacks or data leakage. Organizations in sectors such as e-commerce, media, and public services that rely on Kallyas for their web presence may face reputational damage and compliance issues if sensitive data is exposed. The medium severity reflects the balance between the need for authentication and the limited scope of impact, but the network accessibility and low complexity of exploitation increase the risk profile. European organizations with stringent data protection regulations (e.g., GDPR) must consider the implications of unauthorized data access and ensure timely remediation.

1. Monitor vendor communications closely for official patches addressing CVE-2025-62017 and apply them promptly upon release. 2. Conduct an immediate audit of user roles and permissions within Kallyas installations to ensure the principle of least privilege is enforced, removing unnecessary privileges from users. 3. Implement additional access control mechanisms at the web server or application firewall level to restrict sensitive operations to trusted users or IP ranges where feasible. 4. Enable detailed logging and monitoring of user activities within Kallyas to detect anomalous behavior indicative of exploitation attempts. 5. Consider temporary compensating controls such as disabling non-essential features or endpoints that may be vulnerable until a patch is available. 6. Educate administrators and users about the risk and signs of exploitation to improve incident detection and response. 7. Review and update incident response plans to include scenarios involving unauthorized access due to missing authorization vulnerabilities.
