| 标题 | SeaCMS 13.6 Cross Site Scripting |
|---|
| 描述 | SeaCMS 13.6 `err.php` reflects the user-controlled `errtxt` query parameter inside a `<textarea>` without proper HTML escaping. An unauthenticated attacker can inject `</textarea>` to break out of the element and append arbitrary HTML or JavaScript, resulting in reflected cross-site scripting when a victim opens the crafted URL. |
