EduKart Pro <= 1.0.3 - 認証されていない権限昇格

The impact of CVE-2025-13559 is severe. Successful exploitation allows an attacker to bypass authentication and directly register as an administrator. This grants them complete control over the WordPress site, including the ability to modify content, install malicious plugins, steal sensitive data (user credentials, customer information, financial data), and potentially pivot to other systems on the network. The lack of authentication required for exploitation significantly broadens the attack surface, making it a high-priority concern. This vulnerability shares similarities with other WordPress privilege escalation flaws where improper role assignment during user registration is exploited.

WordPress sites utilizing the EduKart Pro plugin, particularly those with limited security hardening or those running older, unpatched versions, are at significant risk. Shared hosting environments where multiple websites share the same server infrastructure are also at increased risk, as a compromise of one site could potentially lead to the compromise of others.

• wordpress / plugin: Use wp-cli plugin list to identify installations of EduKart Pro. Check plugin files (e.g., edukartproregisteruserfront_end.php) for the vulnerable code. • generic web: Monitor WordPress access logs for POST requests to the registration endpoint with parameters attempting to set the user role to 'administrator'. • wordpress / composer: Run composer audit within the EduKart Pro plugin directory to check for known vulnerabilities. • wordpress / plugin: Use a WordPress security plugin to scan for privilege escalation vulnerabilities and monitor for suspicious user registration attempts.

The primary mitigation for CVE-2025-13559 is to upgrade to a patched version of the EduKart Pro plugin as soon as it becomes available. Until a patch is released, consider temporarily disabling the EduKart Pro plugin to prevent potential exploitation. As a temporary workaround, implement a WordPress plugin that restricts user roles during registration, preventing the assignment of the 'administrator' role to unauthenticated users. Monitor WordPress access logs for suspicious registration attempts, particularly those attempting to assign the administrator role. After upgrade, confirm the vulnerability is resolved by attempting a user registration with the 'administrator' role and verifying that it is rejected.
