CVE-2025-64635 identifies a missing authorization vulnerability in the 'Feeds for YouTube' WordPress plugin developed by Syed Balkhi, affecting all versions up to and including 2.4.0. The vulnerability arises from incorrectly configured access control security levels, which fail to properly restrict unauthorized users from accessing or manipulating certain plugin functionalities. This can lead to unauthorized data access or modification within the context of the plugin, potentially exposing sensitive information or enabling malicious actions on affected WordPress sites. The issue is rooted in the plugin's failure to enforce proper authorization checks before granting access to specific features or data feeds. Although no exploits have been reported in the wild, the vulnerability presents a significant risk due to the plugin's integration with YouTube feeds, which may be used to display or manage content on websites. The vulnerability does not require user interaction and may be exploited remotely, increasing its risk profile. The absence of a CVSS score necessitates an independent severity assessment based on the potential impact and exploitability.

For European organizations, this vulnerability poses a risk of unauthorized access to or manipulation of YouTube feed data integrated into their WordPress sites. This could lead to data confidentiality breaches if sensitive information is exposed or integrity issues if attackers alter displayed content. Organizations relying on this plugin for content delivery or marketing may suffer reputational damage or operational disruptions. Since WordPress is widely used across Europe, especially in countries with large digital economies, the scope of affected systems could be substantial. Attackers exploiting this vulnerability could bypass authentication controls, potentially gaining footholds for further attacks or data exfiltration. The impact is heightened for organizations in sectors such as media, e-commerce, and public services, where content integrity and availability are critical. Although no known exploits exist yet, the vulnerability's nature suggests a high potential for exploitation once a public exploit or automated tool emerges.

Organizations should monitor the vendor's announcements closely and apply security patches immediately once available. Until a patch is released, administrators should implement strict access control measures at the web server or WordPress level to restrict access to plugin functionalities only to trusted users. Employing Web Application Firewalls (WAFs) with custom rules to block unauthorized requests targeting the plugin endpoints can reduce risk. Regularly auditing user permissions and plugin configurations will help identify and close potential access gaps. Additionally, consider disabling or removing the 'Feeds for YouTube' plugin if it is not essential, to eliminate exposure. Security teams should also monitor logs for unusual access patterns related to the plugin and prepare incident response plans for potential exploitation scenarios. Finally, educating site administrators about the risks of outdated plugins and enforcing timely updates is critical.
