CVE-2025-67590 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Rustaurius Ultimate FAQ plugin, versions up to and including 2.4.3. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a malicious request to a web application without their consent, leveraging the user's active session. In this case, the Ultimate FAQ plugin lacks sufficient CSRF protections, such as anti-CSRF tokens or proper request validation, allowing attackers to craft malicious links or web pages that, when visited by an authenticated user, execute unintended actions within the FAQ management interface. The vulnerability has a CVSS 3.1 base score of 4.3, indicating a medium severity primarily due to its network attack vector, low complexity, no privileges required, but requiring user interaction. The impact is limited to confidentiality loss, with no direct integrity or availability consequences. No known exploits have been reported in the wild, and no official patches have been published as of the date of disclosure. The vulnerability affects web applications using the Ultimate FAQ plugin, commonly deployed on WordPress sites, which are prevalent in many European organizations for content management and customer support. The lack of CSRF protections could allow attackers to manipulate FAQ content or settings, potentially leading to misinformation or minor disruptions in user experience. The vulnerability does not require attacker authentication but does require the victim to be authenticated and interact with malicious content. This threat highlights the importance of secure coding practices in web plugins and the need for timely patching and mitigation.

For European organizations, the primary impact of this CSRF vulnerability is the potential unauthorized modification of FAQ content or settings within websites using the Ultimate FAQ plugin. While the confidentiality impact is low, attackers could exploit this to inject misleading information or alter user-facing content, potentially damaging organizational reputation or causing user confusion. Since the vulnerability does not affect integrity or availability directly, critical business operations are unlikely to be disrupted. However, organizations relying heavily on their FAQ sections for customer support or compliance information could face indirect operational impacts. The requirement for user interaction and an authenticated session limits the attack scope but does not eliminate risk, especially for organizations with large user bases or employees frequently accessing administrative interfaces. The absence of known exploits reduces immediate risk but does not preclude future exploitation. European entities with public-facing WordPress sites using this plugin should consider this vulnerability a moderate risk that warrants prompt attention to prevent potential misuse.

To mitigate CVE-2025-67590, organizations should implement the following specific measures: 1) Monitor Rustaurius and Ultimate FAQ plugin updates closely and apply patches immediately once available. 2) If patches are not yet available, deploy Web Application Firewalls (WAFs) with custom rules to detect and block suspicious CSRF-like requests targeting the FAQ plugin endpoints. 3) Enforce strict same-site cookie attributes (SameSite=Lax or Strict) to reduce the risk of cross-origin requests carrying authentication cookies. 4) Review and harden web application security configurations, ensuring that all state-changing requests require anti-CSRF tokens or equivalent validation mechanisms. 5) Educate users and administrators about the risks of clicking on untrusted links while authenticated in administrative interfaces. 6) Conduct regular security assessments and penetration tests focusing on web application vulnerabilities, including CSRF. 7) Consider isolating administrative interfaces behind VPNs or IP whitelisting to reduce exposure. These targeted actions go beyond generic advice and address the specific nature of this CSRF vulnerability in the Ultimate FAQ plugin.
