Stored script execution via unescaped email settings
Published Oct 24, 2023 · Updated Apr 28, 2026
Stored XSS in Mitchell Bennis Simple File List 6.1.9 and earlier allows remote authenticated users to inject scripts through email settings. The email settings form stores some parameters without validating them and later renders their values without escaping, so attacker-controlled markup executes in a viewer's browser. Administrator access and subsequent viewing of the stored content are required, exposing data and actions available to the affected browser session.
