Technical Analysis
CVE-2026-104023 describes an SQL Injection vulnerability (CWE-89) in the Smart Popup by Supsystic WordPress plugin. The flaw exists in all versions up to 1.13.2 and is caused by improper neutralization of special elements in the 'sidx' parameter, which is used in SQL commands without sufficient escaping or prepared statements. Authenticated attackers with administrator privileges can exploit this to append additional SQL queries to existing ones, potentially extracting sensitive data from the database.
Potential Impact
An attacker with administrator-level access can exploit this vulnerability to execute unauthorized SQL queries, leading to the potential disclosure of sensitive information stored in the database. The vulnerability does not affect confidentiality, integrity, or availability beyond data exposure. No evidence of active exploitation in the wild is reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict administrator access to trusted users only and monitor for suspicious activity related to SQL queries involving the 'sidx' parameter.
