CVE-2025-64375 identifies a missing authorization vulnerability in the WP Social Ninja plugin developed by Mahmudul Hasan Arif, affecting versions up to 3.20.1. The vulnerability arises from incorrectly configured access control security levels, which fail to properly enforce authorization checks on certain plugin functionalities. This misconfiguration can allow attackers to perform unauthorized actions, such as accessing or modifying social review data, or potentially manipulating plugin settings without proper privileges. The plugin is widely used in WordPress environments to aggregate and display social media reviews and feeds, making it a valuable target for attackers seeking to compromise website integrity or user trust. Although no public exploits are reported yet, the vulnerability's nature suggests that exploitation could be straightforward, especially if the attacker can interact with the plugin's endpoints directly. The absence of a CVSS score indicates that the vulnerability is newly disclosed and not yet fully assessed, but the missing authorization flaw typically represents a significant security risk. The vulnerability was reserved in late October 2025 and published in December 2025, indicating recent discovery. The lack of patch links suggests that fixes may still be pending or in the process of release, emphasizing the need for vigilance among users of this plugin.

For European organizations, the impact of CVE-2025-64375 can be substantial, particularly for those relying on WP Social Ninja to manage social proof and customer engagement on their WordPress sites. Unauthorized access could lead to data leakage of customer reviews or manipulation of displayed content, undermining customer trust and brand reputation. In e-commerce and service sectors, altered reviews or unauthorized changes could affect purchasing decisions and compliance with consumer protection regulations such as GDPR. Additionally, attackers might leverage this vulnerability as a foothold to escalate privileges or deploy further attacks within the compromised web environment. The impact on confidentiality and integrity is high, while availability impact is likely limited unless combined with other vulnerabilities. Given the widespread use of WordPress and social plugins in Europe, the scope of affected systems is broad, increasing the potential for widespread exploitation if unmitigated.

Organizations should immediately inventory their WordPress installations to identify the presence and version of WP Social Ninja. Until an official patch is released, restrict access to the plugin’s administrative interfaces by implementing strict role-based access controls and IP whitelisting where feasible. Employ Web Application Firewalls (WAFs) to detect and block suspicious requests targeting plugin endpoints. Monitor logs for unusual activity related to WP Social Ninja functions. Once a patch becomes available, prioritize its deployment across all affected systems. Additionally, consider isolating the plugin’s functionality or disabling it temporarily if it is not critical to business operations. Conduct regular security audits of WordPress plugins and maintain an update policy to reduce exposure to similar vulnerabilities. Educate site administrators about the risks of missing authorization flaws and the importance of least privilege principles.
