Database access and script execution via unsanitized inputs
Published May 16, 2026 · Updated May 16, 2026
SQL injection and stored XSS in Supsystic Pricing Table 1.8.6 and 1.8.7 allow remote attackers to query data and execute scripts. The getListForTbl action passes the unsanitized sidx parameter into a database sort expression, while Edit name and Edit HTML store unfiltered markup that later renders with a table. The SQL injection requires no authentication or user interaction; stored script execution requires access to the table editor and affects subsequent table viewers.
