Technical Analysis

CVE-2025-49431 is a security vulnerability classified under CWE-862, which indicates a Missing Authorization issue in the Gnuget MF Plus WPML product. This vulnerability arises due to incorrectly configured access control security levels, allowing unauthorized users to perform actions or access resources that should be restricted. The affected product version is MF Plus WPML up to version 1.1, although the exact affected versions are not fully specified (noted as 'n/a'). The vulnerability is remotely exploitable (AV:N), requires no privileges (PR:N), and no user interaction (UI:N), making it accessible to unauthenticated attackers over the network. The CVSS v3.1 base score is 6.5, categorized as medium severity. The impact vector indicates no confidentiality loss (C:N), but there is integrity (I:L) and availability (A:L) impact, meaning attackers can alter data or disrupt service availability. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability's root cause is the absence of proper authorization checks, which is a critical security control failure that can lead to unauthorized modification or denial of service. Given the nature of MF Plus WPML, which likely integrates with WordPress Multilingual Plugin (WPML) or similar content management systems, this vulnerability could allow attackers to manipulate multilingual content or disrupt website functionality.

Potential Impact

For European organizations, this vulnerability poses a significant risk especially to those relying on the MF Plus WPML plugin for managing multilingual content on their websites. The integrity and availability impacts could lead to unauthorized content modifications, defacement, or denial of service, harming brand reputation and user trust. Organizations in sectors such as e-commerce, government, education, and media that depend on multilingual web presence are particularly vulnerable. Disruption of website availability could affect business continuity and customer engagement. Additionally, unauthorized changes to content could be exploited for misinformation or phishing campaigns targeting European users. The lack of required authentication for exploitation increases the threat level, as attackers can remotely exploit this vulnerability without prior access. Given the GDPR environment, unauthorized data manipulation or service disruption could also lead to regulatory scrutiny if personal data or service availability is impacted.

Mitigation Recommendations

Organizations should immediately audit their use of the MF Plus WPML plugin and verify if they are running affected versions. Since no patches are currently linked, temporary mitigations include restricting network access to the affected plugin's endpoints via web application firewalls (WAFs) or reverse proxies, implementing strict access control policies at the application and server levels, and monitoring logs for suspicious access patterns. Administrators should disable or remove the plugin if it is not essential. Additionally, organizations should prepare to apply vendor patches once available and test updates in staging environments before production deployment. Employing runtime application self-protection (RASP) tools could help detect and block unauthorized access attempts. Regular security assessments and penetration testing focused on authorization controls are recommended to identify similar weaknesses. Finally, organizations should maintain incident response readiness to quickly address any exploitation attempts.
