CVE-2025-25226: 
PHP vulnerability analysis and mitigation

CVE-2025-25226 is a SQL injection vulnerability discovered in the quoteNameStr method of Joomla's Database package. The vulnerability was discovered on March 17, 2025, and was patched on April 2, 2025. This flaw affects Database Package versions 1.0.0-2.1.1 and 3.0.0-3.3.1, and has received a Critical CVSS score of 9.8 (Joomla Security Centre, Daily CyberSecurity).

The vulnerability stems from improper handling of identifiers in the quoteNameStr method of the database package. It's important to note that the affected method is a protected method with no direct usage in the original packages in either the 2.x or 3.x branch. The vulnerability has been assigned a CVSS score of 9.8, indicating critical severity (Daily CyberSecurity).

While the vulnerability cannot be exploited when using the original database class, classes extending the affected class might be vulnerable if they use the vulnerable method. This means that while standard Joomla installations might not be directly at risk, custom extensions or modified classes that utilize this vulnerable method could be highly susceptible to SQL injection attacks (Daily CyberSecurity).

Joomla has released patched versions to address this vulnerability. The recommended solution is to upgrade the Database package to version 2.2.0 or 3.4.0. Website administrators are strongly advised to apply these updates immediately to mitigate the risks (Daily CyberSecurity).
