CVE-2025-24779 is a high-severity vulnerability classified under CWE-502, which pertains to the deserialization of untrusted data. This vulnerability affects the NooTheme Yogi product, specifically versions up to 2.9.0. The core issue arises from the unsafe deserialization process where untrusted input data is deserialized without proper validation or sanitization, allowing an attacker to perform object injection. This can enable remote code execution or other malicious actions by manipulating serialized objects to alter program behavior. The CVSS v3.1 score of 8.8 reflects the critical nature of this flaw, with an attack vector that is network-based (AV:N), requiring low attack complexity (AC:L), and only low privileges (PR:L) but no user interaction (UI:N). The impact covers confidentiality, integrity, and availability, all rated high (C:H/I:H/A:H), indicating that successful exploitation could lead to full system compromise, data leakage, and service disruption. No known exploits are currently reported in the wild, and no patches have been linked yet, which suggests that organizations using this theme should prioritize mitigation and monitoring. The vulnerability is particularly dangerous because deserialization flaws often allow attackers to bypass traditional security controls and execute arbitrary code remotely, making it a critical threat vector in web applications and CMS themes like Yogi.

For European organizations, the impact of CVE-2025-24779 could be significant, especially for those using the NooTheme Yogi theme in their web infrastructure, such as e-commerce platforms, corporate websites, or content management systems. Exploitation could lead to unauthorized access to sensitive customer data, intellectual property theft, defacement of websites, and disruption of online services. Given the high confidentiality, integrity, and availability impacts, organizations could face regulatory penalties under GDPR for data breaches, reputational damage, and financial losses. The fact that the vulnerability requires only low privileges but no user interaction means that attackers could automate exploitation remotely, increasing the risk of widespread attacks. European organizations with limited patch management capabilities or those that heavily customize their CMS environments might be particularly vulnerable. Additionally, sectors such as finance, healthcare, and government, which rely on secure web presence and data confidentiality, could suffer severe consequences if targeted through this vulnerability.

To mitigate CVE-2025-24779, European organizations should take the following specific actions: 1) Immediately inventory all web assets to identify any deployments using NooTheme Yogi, especially versions up to 2.9.0. 2) Apply any available patches or updates from NooTheme as soon as they are released; if no official patch exists, consider temporarily disabling or replacing the Yogi theme with a secure alternative. 3) Implement web application firewalls (WAF) with custom rules to detect and block suspicious serialized payloads or object injection attempts targeting the theme. 4) Conduct code reviews and security testing focused on deserialization processes within the theme or related plugins to identify and remediate unsafe deserialization patterns. 5) Restrict privileges for web application components to the minimum necessary to limit the impact of a potential exploit. 6) Monitor logs and network traffic for unusual activity indicative of exploitation attempts, such as unexpected serialized data or anomalous requests. 7) Educate development and operations teams about the risks of unsafe deserialization and secure coding practices to prevent similar vulnerabilities in the future.
