| Titel | garycourt uri-js 4.4.1 Missing Undefined Check on Mailto URI 'to' Header Parser |
|---|
| Beschreibung | While auditing uri-js's scheme handlers for exception safety, I noticed the mailto handler's query-header parser has four branches (to, subject, body, default) that all handle a missing header value the same way, except one. The to branch skips the guard and calls .split(",") directly on a value that can be undefined, so any mailto URI with a bare to token in the query crashes URI.parse() with an uncaught TypeError. |
