CVE-2025-53219 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the WordPress plugin WP-Database-Optimizer-Tools developed by pl4g4. This vulnerability affects versions up to 0.2 and allows an attacker to trick an authenticated user into submitting unwanted requests to the plugin without their consent. CSRF attacks exploit the trust that a web application places in the user's browser, enabling attackers to perform state-changing actions such as modifying database optimization settings or triggering optimization routines. The CVSS 3.1 base score of 5.4 indicates a medium severity level, reflecting that the vulnerability can be exploited remotely (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R). The impact primarily affects the integrity and availability of the database optimization process, potentially leading to unintended changes or disruptions in database maintenance tasks. No known exploits are currently in the wild, and no patches have been published yet. The vulnerability is categorized under CWE-352, which is a common web security weakness related to CSRF attacks. Since the plugin operates within WordPress environments, the threat surface includes websites using this plugin for database optimization tasks, which may be critical for maintaining website performance and stability.

For European organizations, this vulnerability poses a risk primarily to websites and web applications running WordPress with the WP-Database-Optimizer-Tools plugin installed. Successful exploitation could lead to unauthorized modifications of database optimization settings or execution of optimization routines, potentially causing database performance degradation or downtime. This could affect e-commerce platforms, corporate websites, and service portals relying on WordPress, leading to service disruptions and loss of user trust. Although the vulnerability does not directly compromise confidentiality, the integrity and availability of database operations are at risk. Organizations in sectors with high reliance on WordPress for customer-facing or internal applications—such as retail, media, and public services—may experience operational impacts. Additionally, the requirement for user interaction means phishing or social engineering campaigns could be leveraged to exploit this vulnerability, increasing the risk profile. Given the widespread use of WordPress in Europe, the vulnerability could have a broad impact if exploited at scale.

To mitigate this vulnerability, European organizations should first verify if they are using the WP-Database-Optimizer-Tools plugin, especially versions up to 0.2. Immediate steps include disabling or uninstalling the plugin until a security patch is released. Administrators should implement anti-CSRF tokens in all state-changing requests within the plugin to ensure that requests originate from legitimate users. Web application firewalls (WAFs) can be configured to detect and block suspicious CSRF attack patterns targeting the plugin endpoints. User education is critical to reduce the risk of social engineering attacks that could trigger CSRF exploits; users should be trained to avoid clicking on suspicious links while authenticated to sensitive systems. Monitoring and logging of database optimization activities should be enhanced to detect unusual or unauthorized operations. Finally, organizations should stay alert for official patches or updates from the vendor and apply them promptly once available.
