Summary
by MITRE • 06/19/2026
Joomla! Component Price Alert 3.0.2 contains an SQL injection vulnerability that allows unauthenticated attackers to execute arbitrary SQL queries by injecting malicious code through the product_id parameter. Attackers can send requests to the subscribeajax view with crafted SQL payloads in the product_id parameter to extract sensitive database information including credentials and configuration data.

The Joomla! Component Price Alert version 3.0.2 suffers from a critical SQL injection vulnerability that represents a severe threat to web application security and database integrity. This vulnerability exists within the component's subscribeajax view functionality where the product_id parameter is improperly sanitized and directly incorporated into SQL queries without adequate input validation or parameterization. The flaw allows unauthenticated attackers to manipulate the application's database interactions by injecting malicious SQL code through the product_id parameter, effectively bypassing normal authentication mechanisms and access controls that should protect sensitive database resources.
The technical exploitation of this vulnerability follows a well-established pattern that aligns with CWE-89 SQL Injection, where user-supplied input is concatenated directly into SQL command strings rather than being properly escaped or parameterized. When an attacker submits a crafted request to the subscribeajax view with malicious SQL payloads in the product_id parameter, the application processes this input without proper sanitization, enabling the execution of arbitrary SQL commands against the underlying database. This vulnerability operates at the application layer and can be exploited through standard HTTP requests, making it particularly dangerous as it requires no prior authentication credentials or specialized tools beyond basic web exploitation techniques.
The operational impact of this vulnerability extends beyond simple data exfiltration to encompass complete database compromise and potential system infiltration. Attackers can leverage this vulnerability to extract sensitive information including user credentials, administrative access details, configuration parameters, and other confidential data stored within the database. The vulnerability's unauthenticated nature means that any external party can exploit it without requiring legitimate user accounts or elevated privileges, significantly increasing the attack surface and potential damage. This type of vulnerability directly maps to attack techniques described in the MITRE ATT&CK framework under the T1190 Exploit Public-Facing Application tactic, where adversaries target vulnerabilities in web applications to gain unauthorized access to backend systems.
Mitigation strategies for this vulnerability should prioritize immediate patching of the affected Joomla installation. Regular security monitoring and vulnerability scanning should be maintained to ensure early detection of similar issues and to verify that patches have been properly applied across all affected systems.
