| Mô tả | The affected components are `application/PHP/objects/notes/add_into_dictionary.php`, `application/PHP/objects/notes/display_dictionary.php`, `application/PHP/classes/Notes_controller.php`, and `application/JS/notes.js`. Dictionary entries store user-controlled `reference` values and later render them into HTML without escaping:
```php
$insert_definition_statement = $this->db_holder->prepare("INSERT INTO definitions VALUES (null, ?, ?);");
$insert_definition_statement->execute(array($definition, $reference));
...
$dictionary = $dictionary."<p>".nl2br(htmlentities($data[0]))."<br />
<span id='no_dictionary_added_by'>Added by: ".$data[2]."</span><br />
<span>Reference: ".$data[1]."</span>
</p>";
```
The client inserts the returned HTML with `.html(data)`:
```javascript
$("#no_display_dictionary_container_div").html(data);
```
An authenticated attacker can store payloads such as `<svg/onload=alert()>` in the reference field. When another user views the dictionary entry, the payload executes in that user's browser. |
