CVE-2025-58595 is an authentication bypass vulnerability identified in the Saad Iqbal All In One Login WordPress plugin, specifically affecting versions up to and including 2.0.8. The vulnerability arises from an identity spoofing mechanism within the plugin’s change-wp-admin-login feature, which is intended to modify or obscure the WordPress admin login URL. Due to improper validation of authentication tokens or session parameters, an attacker can bypass normal authentication controls without any privileges or user interaction. This allows the attacker to impersonate legitimate users, including administrators, thereby gaining unauthorized access to the WordPress admin dashboard. The vulnerability is remotely exploitable over the network (AV:N), requires no privileges (PR:N), and no user interaction (UI:N), making it highly accessible to attackers. The impact on confidentiality and integrity is high, as attackers can view, modify, or delete sensitive data and potentially deploy malicious code or backdoors. Availability impact is not significant. Although no public exploits are reported yet, the critical CVSS score of 9.1 reflects the severity and ease of exploitation. The vulnerability was reserved in early September 2025 and published in November 2025, indicating recent discovery and disclosure. The lack of available patches at the time of reporting increases the urgency for mitigation.

For European organizations, this vulnerability poses a significant threat to WordPress-based websites, including corporate portals, e-commerce platforms, and government services that rely on the Saad Iqbal All In One Login plugin. Successful exploitation can lead to unauthorized administrative access, data breaches involving personal and financial information, defacement of websites, and potential use of compromised sites as launchpads for further attacks. The breach of confidentiality and integrity can damage organizational reputation, result in regulatory penalties under GDPR, and disrupt business operations. Given the widespread use of WordPress in Europe and the critical nature of the vulnerability, the risk is elevated for sectors with high-value targets such as finance, healthcare, and public administration. The absence of known exploits currently provides a window for proactive defense, but the ease of exploitation and lack of required authentication increase the likelihood of future attacks.

1. Immediately update the Saad Iqbal All In One Login plugin to a patched version once available from the vendor or disable the plugin until a fix is released. 2. Implement web application firewall (WAF) rules to block suspicious requests targeting the login URL or attempts to spoof authentication tokens. 3. Restrict access to the WordPress admin login page by IP whitelisting or VPN-only access for administrative users. 4. Monitor WordPress logs for unusual login attempts or access patterns indicative of exploitation attempts. 5. Employ multi-factor authentication (MFA) on WordPress admin accounts to add an additional layer of security. 6. Regularly audit installed plugins and remove any that are unnecessary or unsupported. 7. Maintain regular backups of website data and configurations to enable rapid recovery in case of compromise. 8. Educate site administrators about the risks of using plugins with known vulnerabilities and encourage timely patch management.
