CVE-2025-14906 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability identified in the WP Youtube Video Gallery plugin for WordPress, affecting all versions up to and including 1.0. The root cause is the absence of nonce verification in the wpYTVideoGallerySettingSave() function, which is responsible for saving plugin settings. Nonce verification is a security mechanism in WordPress that helps ensure that requests to change settings originate from legitimate users and not from forged requests. Due to this missing check, an attacker can craft a malicious URL or webpage that, when visited by a logged-in WordPress administrator, triggers unauthorized changes to the plugin’s settings without their consent. This attack vector requires user interaction (clicking a link) but does not require the attacker to be authenticated. The vulnerability impacts the integrity of the plugin’s configuration but does not directly compromise confidentiality or availability of the system. Although no known exploits are currently reported in the wild, the vulnerability is publicly disclosed and could be weaponized in targeted phishing campaigns. The CVSS v3.1 base score is 4.3, reflecting the ease of exploitation combined with limited impact scope. The vulnerability is cataloged under CWE-352, which is the standard classification for CSRF issues. No official patches or updates have been linked yet, so mitigation relies on manual code fixes or administrative controls.

For European organizations, this vulnerability poses a risk primarily to the integrity of WordPress sites using the WP Youtube Video Gallery plugin. Attackers can alter plugin settings, potentially enabling malicious configurations such as redirecting video content, injecting unwanted scripts, or disrupting user experience. While it does not directly expose sensitive data or cause denial of service, unauthorized changes can undermine trust in the affected websites and may serve as a foothold for further attacks. Organizations with public-facing WordPress sites, especially those relying on video content for marketing or communication, could suffer reputational damage. The requirement for administrator interaction means that phishing or social engineering campaigns targeting site admins are a likely exploitation vector. Given the widespread use of WordPress across Europe, the threat is relevant but limited to sites using this specific plugin. The absence of known exploits reduces immediate risk but does not eliminate it, especially as attackers often weaponize disclosed vulnerabilities rapidly.

1. Implement nonce verification in the wpYTVideoGallerySettingSave() function to ensure that all requests to modify plugin settings are legitimate and originate from authorized users. This involves adding WordPress’s built-in nonce checks in the plugin’s codebase. 2. Until an official patch is released, restrict administrative access to trusted networks or use multi-factor authentication (MFA) to reduce the risk of compromised admin accounts. 3. Educate WordPress administrators about the risks of phishing and social engineering, emphasizing caution when clicking links, especially those received via email or untrusted sources. 4. Monitor administrative actions and plugin settings for unexpected changes to detect potential exploitation attempts early. 5. Consider temporarily disabling or replacing the WP Youtube Video Gallery plugin if it is not critical to operations. 6. Keep WordPress core and all plugins updated regularly to minimize exposure to known vulnerabilities. 7. Employ web application firewalls (WAFs) that can detect and block CSRF attack patterns or suspicious requests targeting administrative endpoints.
