CVE-2026-56738: CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in thorsten phpMyFAQ
phpMyFAQ versions prior to 4.1.6 contain an SQL injection vulnerability in the StopWords::add() method. This method improperly constructs an SQL INSERT statement by directly inserting user-supplied input without proper escaping. An authenticated administrator with access to the stop-word management feature can exploit this to inject arbitrary SQL commands. The issue is fixed in version 4.1.6.
AI Analysis
Technical Summary
The vulnerability in phpMyFAQ arises from the StopWords::add() method, which uses sprintf() to build an SQL INSERT statement and inserts user input directly without escaping. This allows an authenticated administrator to inject arbitrary SQL via the 'word' parameter, potentially leading to data manipulation or destruction. The StopWords::update() method correctly escapes input, isolating the flaw to the add() path. Version 4.1.6 addresses this issue by applying proper escaping.
Potential Impact
An authenticated administrator can exploit this vulnerability to execute arbitrary SQL commands, including dropping tables, exfiltrating data, or modifying database rows. This can compromise the integrity and confidentiality of the application's database.
Mitigation Recommendations
Upgrade phpMyFAQ to version 4.1.6 or later, where this SQL injection vulnerability has been fixed. No additional mitigation is required once the update is applied.
