CVE-2025-52795 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the WordPress plugin 'WP Front User Submit / Front Editor' developed by aharonyan. This plugin enables front-end content submission and editing capabilities for WordPress sites, allowing users to submit or modify content without accessing the WordPress backend. The vulnerability affects all versions up to 4.9.4. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged request to a web application, causing the application to perform unwanted actions on behalf of the user. In this case, the vulnerability allows an attacker to craft malicious requests that, when executed by an authenticated user with sufficient privileges, can modify content or perform other actions permitted by the plugin. The CVSS v3.1 base score is 7.1 (high severity), with vector AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H, indicating that the attack can be performed remotely over the network with low attack complexity, no privileges required, but requires user interaction (e.g., clicking a link). The impact affects integrity (I:L) and availability (A:H) but not confidentiality. The vulnerability does not require prior authentication, but user interaction is necessary. No known exploits are currently in the wild, and no patches have been published yet. The absence of patches suggests that sites using this plugin remain vulnerable until an update is released or mitigations are applied. Given the plugin’s role in content submission and editing, exploitation could lead to unauthorized content changes, defacement, or denial of service by disrupting content availability or functionality.

For European organizations, especially those relying on WordPress for public-facing websites, this vulnerability poses a significant risk. Organizations using the WP Front User Submit / Front Editor plugin may face unauthorized content modifications, which can damage brand reputation, misinform users, or violate compliance requirements related to content integrity. The availability impact could disrupt website operations, affecting customer engagement and business continuity. Since the vulnerability requires user interaction but no authentication, attackers could target users through phishing campaigns or malicious links, increasing the attack surface. Sectors such as media, e-commerce, education, and government entities that use WordPress extensively for content management are particularly at risk. Additionally, compromised websites could be leveraged to distribute malware or conduct further attacks, amplifying the threat. The lack of patches increases exposure time, making timely mitigation critical.

1. Immediate mitigation should include disabling or removing the WP Front User Submit / Front Editor plugin until a security patch is available. 2. Implement Web Application Firewall (WAF) rules to detect and block suspicious CSRF attempts targeting the plugin’s endpoints. 3. Enforce strict Content Security Policy (CSP) headers to reduce the risk of malicious script execution that could facilitate CSRF attacks. 4. Educate users and administrators about the risks of clicking unsolicited links, especially those that could trigger state-changing requests. 5. Monitor web server and application logs for unusual POST requests or patterns indicative of CSRF exploitation attempts. 6. If disabling the plugin is not feasible, consider restricting access to the plugin’s front-end submission forms via IP whitelisting or CAPTCHA challenges to reduce automated exploitation risk. 7. Regularly back up website content and configurations to enable rapid restoration in case of compromise. 8. Stay alert for official patches or updates from the vendor and apply them promptly once available.
