CVE-2025-62958 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Simple Content Templates for Blog Posts & Pages plugin developed by Clifton Griffin, affecting all versions up to and including 2.2.61. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged HTTP request, which the vulnerable application processes as legitimate. In this case, the plugin lacks sufficient CSRF protections, such as anti-CSRF tokens or proper request validation, allowing remote attackers to induce authenticated users to perform unintended actions on blog post templates. The vulnerability requires no privileges (PR:N) and can be exploited remotely over the network (AV:N) with low attack complexity (AC:L), though user interaction (UI:R) is necessary, typically involving the victim visiting a malicious website. The impact is severe, affecting confidentiality, integrity, and availability (C:H/I:H/A:H), as attackers can alter or delete content templates, potentially defacing websites, injecting malicious content, or disrupting content management workflows. The vulnerability is unpatched as of the publication date (October 27, 2025), and no known exploits have been reported in the wild yet. However, the high CVSS score (8.8) underscores the critical nature of this flaw. The plugin is commonly used in WordPress environments to streamline blog post and page template management, making it a valuable target for attackers seeking to compromise content integrity or launch further attacks through compromised sites.

For European organizations, the impact of CVE-2025-62958 can be substantial. Many businesses, media outlets, and public institutions rely on WordPress and associated plugins like Simple Content Templates for managing web content. Exploitation could lead to unauthorized content changes, defacement, or injection of malicious scripts, undermining user trust and potentially violating data protection regulations such as GDPR if personal data is exposed or manipulated. The availability of content management systems could also be disrupted, affecting business operations and communications. Given the plugin’s role in templating, attackers might also leverage this vulnerability as a foothold for further compromise, including privilege escalation or lateral movement within organizational networks. The lack of required privileges for exploitation increases risk, as any authenticated user can be targeted via social engineering or phishing to trigger the attack. This threat is particularly relevant for sectors with high web presence and regulatory scrutiny, including finance, healthcare, government, and media organizations across Europe.

To mitigate CVE-2025-62958, European organizations should immediately audit their WordPress environments to identify installations of the Simple Content Templates for Blog Posts & Pages plugin. Since no patch links are currently available, interim mitigations include: 1) Restricting access to authenticated users with administrative or content management privileges to trusted personnel only, minimizing the risk of CSRF exploitation via compromised user sessions. 2) Implementing web application firewall (WAF) rules to detect and block suspicious CSRF-like requests targeting the plugin’s endpoints. 3) Enforcing strict Content Security Policies (CSP) and SameSite cookie attributes to reduce the risk of cross-origin request forgery. 4) Monitoring logs for unusual POST requests or template modifications that could indicate exploitation attempts. 5) Encouraging users to avoid clicking on untrusted links while authenticated to the affected sites. 6) Preparing to apply official patches or updates from Clifton Griffin as soon as they are released. Additionally, organizations should review their overall WordPress security posture, including regular updates, least privilege principles, and multi-factor authentication for administrative accounts.
