CVE-2025-64375 identifies a missing authorization vulnerability in the WP Social Ninja plugin developed by Mahmudul Hasan Arif, affecting versions up to and including 3.20.1. This vulnerability arises from incorrectly configured access control mechanisms within the plugin, allowing unauthenticated remote attackers to access or manipulate certain plugin functionalities or data that should be restricted. The vulnerability is exploitable over the network without any privileges or user interaction, increasing its risk profile. The CVSS 3.1 base score is 6.5, indicating a medium severity level, with impacts primarily on confidentiality and integrity but no impact on availability. The flaw could allow attackers to view or alter social review data or plugin settings, potentially undermining trustworthiness of displayed social proof or exposing sensitive user information. No known public exploits or patches are currently available, but the vulnerability has been publicly disclosed and assigned a CVE identifier. The plugin is widely used in WordPress environments to integrate social media reviews and feeds, making affected sites potential targets for exploitation. The vulnerability underscores the importance of proper access control validation in WordPress plugins, especially those handling user-generated content or third-party integrations.

For European organizations, the vulnerability could lead to unauthorized disclosure or modification of social review data displayed on websites, impacting brand reputation and customer trust. Attackers exploiting this flaw might manipulate displayed reviews or extract sensitive information, which could be used for social engineering or competitive intelligence. While the vulnerability does not directly affect availability, the integrity compromise could indirectly harm business operations reliant on authentic social proof. Organizations in sectors such as e-commerce, digital marketing, and hospitality that heavily rely on social reviews are particularly at risk. Additionally, regulatory compliance concerns may arise if personal data is exposed, potentially triggering GDPR implications. The ease of exploitation without authentication increases the threat surface, especially for publicly accessible websites. However, the absence of known exploits in the wild and the medium severity rating suggest that immediate widespread impact is limited but should not be underestimated.

Organizations should monitor for official patches or updates from the WP Social Ninja plugin developer and apply them promptly once available. Until a patch is released, administrators can implement custom access control measures at the web server or application firewall level to restrict access to sensitive plugin endpoints. Conducting a thorough audit of plugin permissions and configurations can help identify and close unintended access paths. Employing security plugins that monitor and block suspicious requests targeting WordPress plugins can provide additional protection. Regularly reviewing website logs for unusual access patterns related to WP Social Ninja endpoints is recommended. Organizations should also consider isolating or disabling the plugin if it is not critical to business operations until the vulnerability is resolved. Finally, educating website administrators about the risks of unauthorized access and the importance of timely updates is essential to reduce exposure.
