The Simple File List WordPress plugin through 6.3.11 does not properly sanitise and escape a file's description before outputting it on the public file list, allowing unauthenticated users (when front-end file management is enabled) to perform Stored Cross-Site Scripting attacks that execute in the browser of any visitor viewing the list.
