CVE-2025-9073 is a high-severity SQL Injection vulnerability affecting the 'All in one Minifier' WordPress plugin developed by maheshmthorat. This vulnerability exists in all versions up to and including 3.2 of the plugin. The root cause is improper neutralization of special elements used in SQL commands (CWE-89), specifically due to insufficient escaping and lack of prepared statements for the 'post_id' parameter. This parameter is user-supplied and unauthenticated attackers can manipulate it to inject arbitrary SQL code into existing queries. Exploitation allows attackers to append additional SQL queries, potentially extracting sensitive information from the backend database. The vulnerability does not require authentication or user interaction, and the attack vector is network accessible (via the web). The CVSS v3.1 base score is 7.5, reflecting high severity with high confidentiality impact but no impact on integrity or availability. No known exploits in the wild have been reported yet, and no patches have been linked at the time of publication. Given the widespread use of WordPress and the popularity of plugins for site optimization, this vulnerability poses a significant risk to websites using this plugin, especially if they handle sensitive data or have privileged database access.

For European organizations, this vulnerability could lead to unauthorized disclosure of sensitive data stored in WordPress databases, including user credentials, personal data protected under GDPR, and business-critical information. Since the vulnerability allows data extraction without authentication, attackers can leverage it to conduct reconnaissance or data theft, potentially leading to privacy violations and compliance breaches. The impact is particularly severe for organizations relying on WordPress for customer-facing websites, e-commerce platforms, or internal portals. Data leakage could result in reputational damage, regulatory fines, and loss of customer trust. Additionally, the vulnerability could be chained with other exploits to escalate attacks or pivot within the network. The lack of integrity and availability impact reduces the risk of destructive attacks but does not diminish the confidentiality risks. European organizations must consider the GDPR implications of data breaches resulting from this vulnerability.

Immediate mitigation steps include disabling or uninstalling the 'All in one Minifier' plugin until a secure patched version is released. Organizations should monitor official vendor channels and WordPress plugin repositories for updates addressing this vulnerability. In the interim, web application firewalls (WAFs) can be configured to detect and block suspicious SQL injection patterns targeting the 'post_id' parameter. Implementing strict input validation and sanitization at the application level can reduce risk, although this requires code changes. Database access permissions should be minimized, ensuring the WordPress database user has only necessary privileges to limit data exposure. Regular security audits and vulnerability scanning should be conducted to identify the presence of this plugin and assess exposure. Logging and monitoring of web application logs for unusual query patterns can help detect exploitation attempts. Finally, organizations should have an incident response plan ready to address potential data breaches stemming from this vulnerability.
