CVE-2025-57969 is a Missing Authorization vulnerability (CWE-862) found in the WordPress plugin 'Hide WP Toolbar' developed by Jeremy Saxey. This vulnerability arises due to incorrectly configured access control security levels, allowing users with some level of privileges (PR:L - Low privileges) to perform actions or access functionalities that should be restricted. The vulnerability affects versions up to 2.7 of the plugin. The CVSS 3.1 base score is 4.3, indicating a medium severity level. The vector string (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N) shows that the attack can be performed remotely over the network without user interaction, requires low privileges, and impacts integrity but not confidentiality or availability. Specifically, the vulnerability does not allow attackers to read sensitive data but can allow unauthorized modification of data or settings related to the plugin's functionality, potentially leading to unauthorized changes in the WordPress environment. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is significant because the 'Hide WP Toolbar' plugin is used to control the visibility of the WordPress admin toolbar, which can affect user interface and administrative experience. Improper authorization could allow low-privileged users to manipulate toolbar visibility or related settings, potentially enabling privilege escalation or information disclosure indirectly by altering the admin UI experience.

For European organizations using WordPress sites with the 'Hide WP Toolbar' plugin, this vulnerability could lead to unauthorized changes in the administrative interface, potentially confusing or misleading administrators or editors. While the direct impact on confidentiality and availability is low, integrity is affected, which could result in unauthorized configuration changes. This could be leveraged as part of a broader attack chain, especially in environments where multiple users have varying privilege levels. Organizations in sectors with strict compliance requirements (e.g., finance, healthcare, government) may face increased risk if unauthorized changes lead to misconfigurations or indirect exposure of sensitive administrative functions. The medium severity and low complexity of exploitation mean that attackers with limited privileges could exploit this vulnerability remotely without user interaction, increasing the risk in multi-user WordPress environments common in European SMEs and enterprises.

1. Immediate review and restriction of user privileges in WordPress to ensure that only trusted users have low-level privileges that could exploit this vulnerability. 2. Monitor and audit changes to the WordPress admin toolbar settings and plugin configurations to detect unauthorized modifications. 3. Disable or remove the 'Hide WP Toolbar' plugin if it is not essential, especially until a security patch is released. 4. Implement Web Application Firewall (WAF) rules to detect and block suspicious requests targeting the plugin's endpoints. 5. Follow vendor advisories closely and apply patches or updates as soon as they become available. 6. Conduct internal penetration testing focusing on access control mechanisms within WordPress plugins to identify similar authorization issues. 7. Educate administrators and users about the risks of privilege misuse and enforce strong access control policies within WordPress environments.
