CVE-2025-58202 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the Simple Page Access Restriction plugin developed by Plugins and Snippets. This vulnerability affects versions up to 1.0.32. CSRF vulnerabilities allow an attacker to trick an authenticated user into submitting a forged HTTP request to a web application, causing the user to perform unwanted actions without their consent. In this case, the vulnerability exists because the plugin does not adequately verify the origin or intent of requests that modify access restrictions on pages. The CVSS 3.1 base score is 4.3, indicating a medium severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N) reveals that the attack can be executed remotely over the network without privileges, requires user interaction (the victim must click or visit a malicious link), and impacts the integrity of the system by allowing unauthorized changes to access restrictions. Confidentiality and availability are not affected. No known exploits are currently in the wild, and no patches have been linked yet. The vulnerability falls under CWE-352, which is a common web security weakness related to CSRF attacks. This issue could allow attackers to bypass or alter page access restrictions by leveraging authenticated users' sessions, potentially leading to unauthorized content exposure or modification of access controls.

For European organizations, the impact of this vulnerability depends on the extent to which they use the Simple Page Access Restriction plugin to control access to sensitive or confidential web content. If exploited, attackers could manipulate page access settings without authorization, potentially exposing restricted information or disrupting access policies. This could lead to unauthorized disclosure of sensitive data or compliance violations, especially under regulations such as GDPR that mandate strict access controls and data protection. While the vulnerability does not directly compromise confidentiality or availability, the integrity impact could undermine trust in web applications and lead to indirect consequences such as data leakage or reputational damage. Organizations relying on this plugin for critical access control should be particularly cautious, as attackers could leverage CSRF to escalate privileges or bypass intended restrictions. The requirement for user interaction means phishing or social engineering could be used to trigger the exploit, increasing the risk in environments with less security awareness.

To mitigate this vulnerability, European organizations should first verify if they use the Simple Page Access Restriction plugin and identify affected versions (up to 1.0.32). Since no patch links are currently available, organizations should monitor vendor advisories for updates or patches addressing CVE-2025-58202. In the interim, administrators can implement the following specific measures: 1) Enforce strict anti-CSRF tokens on all state-changing requests within the plugin to ensure requests originate from legitimate sources. 2) Implement Content Security Policy (CSP) headers to reduce the risk of malicious cross-origin requests. 3) Educate users about phishing and social engineering risks to reduce the likelihood of user interaction leading to exploitation. 4) Restrict the plugin's administrative interface to trusted IP ranges or VPN access to limit exposure. 5) Conduct regular audits of access control configurations to detect unauthorized changes promptly. 6) Consider disabling or replacing the plugin with alternatives that have robust CSRF protections until a patch is available. These targeted actions go beyond generic advice by focusing on the plugin's specific attack vector and operational context.
