CVE-2025-9200 is a high-severity SQL Injection vulnerability affecting the Blappsta Mobile App Plugin for WordPress, which supports native mobile iPhone and Android applications. The vulnerability exists in the nh_ynaa_comments() function across all plugin versions up to and including 0.8.8.8. Due to improper neutralization of special elements in SQL commands (CWE-89), the plugin fails to adequately escape user-supplied input and does not use prepared statements or parameterized queries. This flaw allows unauthenticated attackers to inject malicious SQL code into existing queries, potentially enabling them to extract sensitive data from the backend database. The vulnerability is remotely exploitable over the network without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). Although no known exploits are currently reported in the wild, the ease of exploitation combined with the potential for data confidentiality breaches makes this a critical concern for organizations using this plugin. The lack of available patches at the time of publication further increases risk, necessitating immediate mitigation efforts. The vulnerability impacts the confidentiality of data but does not affect integrity or availability directly. The plugin’s role in integrating mobile app functionality with WordPress sites means that compromised sites could expose user data or internal information managed via the plugin’s database interactions.

For European organizations, this vulnerability poses a significant risk to the confidentiality of sensitive data stored in WordPress databases linked to the Blappsta Mobile App Plugin. Organizations using this plugin to support mobile app interactions may face unauthorized data disclosure, including user comments or other stored information. This could lead to breaches of GDPR requirements concerning personal data protection, resulting in regulatory penalties and reputational damage. The vulnerability’s unauthenticated remote exploitability means attackers can target affected sites at scale, increasing the likelihood of widespread data leaks. Additionally, organizations in sectors with high mobile app usage integrated with WordPress—such as e-commerce, media, and service providers—are particularly vulnerable. The absence of patches means that organizations must rely on alternative mitigations until an official fix is released. Failure to address this vulnerability could also facilitate further attacks, such as data harvesting or lateral movement within compromised environments.

European organizations should immediately audit their WordPress installations to identify the presence of the Blappsta Mobile App Plugin and confirm the version in use. Until a patch is available, it is advisable to disable or uninstall the plugin to eliminate the attack surface. If disabling is not feasible, organizations should implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection payloads targeting the nh_ynaa_comments() function parameters. Input validation and sanitization should be enforced at the application level where possible. Monitoring database query logs for unusual or malformed queries can help detect exploitation attempts early. Organizations should also ensure that database user accounts used by WordPress have the minimum necessary privileges to limit data exposure in case of compromise. Regular backups of the database should be maintained to enable recovery if data integrity is later impacted. Finally, organizations should subscribe to vendor advisories and security mailing lists to promptly apply patches once released.
