CVE-2025-58670 is a high-severity vulnerability affecting the WordPress plugin 'WP Content Protection' developed by Shankaranand Maurya. The vulnerability is classified as a Cross-Site Request Forgery (CSRF) issue (CWE-352) that enables an attacker to perform unauthorized actions on behalf of an authenticated user. Specifically, this CSRF flaw allows an attacker to inject stored Cross-Site Scripting (XSS) payloads into the plugin's content protection mechanisms. The vulnerability affects all versions of WP Content Protection up to and including version 1.3. The CVSS v3.1 base score is 7.1, indicating a high severity level. The vector string (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L) reveals that the attack can be executed remotely over the network without privileges or authentication, requires low attack complexity, but does require user interaction (such as the victim clicking a crafted link). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact includes low confidentiality, integrity, and availability impacts, but combined with stored XSS, it can lead to session hijacking, privilege escalation, or persistent defacement. No patches or known exploits are currently reported, but the vulnerability is publicly disclosed as of September 22, 2025. The vulnerability arises because the plugin fails to implement proper anti-CSRF tokens or validation, allowing malicious third-party sites to trick authenticated users into submitting unauthorized requests that inject malicious scripts stored within the plugin's data. This can compromise site visitors and administrators alike, potentially leading to broader site compromise or data leakage.

For European organizations using WordPress sites with the WP Content Protection plugin, this vulnerability poses a significant risk. The stored XSS enabled by CSRF can lead to session hijacking of administrators, allowing attackers to gain elevated privileges and potentially take over the entire website. This can result in defacement, data theft, or the distribution of malware to site visitors. Given the plugin's role in content protection, exploitation could undermine trust in protected content, impacting media companies, e-commerce platforms, and educational institutions that rely on content access controls. Additionally, GDPR implications arise if personal data is exposed or manipulated due to the attack. The remote and unauthenticated nature of the attack increases the risk of widespread exploitation, especially if attackers craft phishing campaigns targeting site administrators or editors. The lack of known exploits currently suggests a window for proactive mitigation before active exploitation occurs.

European organizations should immediately audit their WordPress installations to identify the presence of the WP Content Protection plugin, particularly versions up to 1.3. Since no official patch is currently available, temporary mitigations include disabling or uninstalling the plugin until a secure update is released. Implementing Web Application Firewall (WAF) rules to detect and block CSRF attack patterns and suspicious POST requests targeting the plugin's endpoints can reduce risk. Administrators should enforce strict Content Security Policy (CSP) headers to limit the impact of stored XSS payloads. Additionally, educating site administrators about phishing and social engineering risks can reduce the likelihood of user interaction required for exploitation. Monitoring logs for unusual administrative actions or unexpected content changes can help detect attempted exploitation. Once a patch is released, organizations must prioritize timely updates. For long-term security, adopting plugins with robust security practices, including built-in CSRF protections and regular security audits, is recommended.
