CVE-2025-53318 is a security vulnerability identified in the WPManiax WP DB Booster WordPress plugin, specifically affecting versions up to 1.0.1. The vulnerability is categorized under CWE-862, which refers to Missing Authorization. This means that the plugin fails to properly enforce access control checks, allowing users with limited privileges (with some level of authentication) to perform actions or access functionality that should be restricted. The CVSS 3.1 base score of 5.4 (medium severity) reflects that the vulnerability can be exploited remotely over the network (AV:N) with low attack complexity (AC:L), requiring privileges (PR:L) but no user interaction (UI:N). The impact primarily affects confidentiality (C:L) and availability (A:L), with no impact on integrity (I:N). This suggests that an attacker with some authenticated access could potentially access or trigger database operations that could leak some data or disrupt availability, but not modify data. The vulnerability arises from incorrectly configured access control security levels within the plugin, which is designed to optimize or boost WordPress database performance. Since no patches or exploits are currently known, the risk is theoretical but should be addressed promptly. The absence of a patch link indicates that a fix may not yet be available, requiring users to monitor vendor updates or apply temporary mitigations. Given the plugin’s role in database management, exploitation could lead to partial data exposure or denial of service conditions impacting website functionality.

For European organizations using WordPress websites with the WP DB Booster plugin, this vulnerability could lead to unauthorized access to certain database operations or data, potentially exposing sensitive information or causing service disruptions. Although the impact on integrity is not indicated, availability degradation could affect business continuity, especially for e-commerce, government, or financial service websites relying on WordPress. Confidentiality loss, even if limited, could contravene GDPR requirements, leading to regulatory scrutiny and fines. The requirement for some level of authentication reduces the risk from anonymous attackers but does not eliminate insider threats or compromised accounts. Organizations with large WordPress deployments or those using WP DB Booster in multi-user environments are at higher risk. The lack of known exploits in the wild currently lowers immediate threat levels but does not preclude future exploitation attempts. The medium severity rating suggests that while this is not a critical emergency, timely remediation is important to maintain security posture and compliance.

European organizations should first inventory their WordPress installations to identify the presence of the WP DB Booster plugin and its version. If detected, restrict access to the WordPress admin panel and database management features to trusted users only, implementing strong authentication and role-based access controls. Monitor user activity logs for unusual access patterns related to database operations. Until an official patch is released, consider disabling or uninstalling the WP DB Booster plugin if it is not essential. For environments where the plugin is critical, implement web application firewalls (WAF) with custom rules to detect and block suspicious requests targeting database booster functionalities. Regularly update WordPress core and plugins to the latest versions once patches become available. Additionally, conduct security awareness training for administrators to recognize and report suspicious behavior. Finally, ensure backups are current and tested to enable recovery in case of availability impact.
