Technical details
The vulnerability is a cross-site scripting (XSS) flaw in the HTML profile of SQL::Abstract::Tree, which generates HTML markup for formatted SQL output. The format() method failed to HTML-escape SQL identifiers, literals, operators, and filled-in bind values before inserting them around the profile's own span and br markup. An attacker controlling a bind value (e.g., user input used in a WHERE clause) or SQL string literal can embed script tags that execute in the page context.
