### Summary One of the sample scripts in PhpSpreadsheet is susceptible to a cross-site scripting (XSS) vulnerability due to improper handling of input where a number is expected leading to formula injection. ### Details The following [code](https://github.com/PHPOffice/PhpSpreadsheet/blob/d50b8b5de7e30439fb57eae7df9ea90e79fa0f2d/samples/Basic/45_Quadratic_equation_solver.php#L56) in `45_Quadratic_equation_solver.php` concatenates the user supplied parameters directly into spreadsheet formulas. This allows an attacker to take control over the formula and output unsanitized data into the page, resulting in JavaScript execution. ``` $discriminantFormula = '=POWER(' . $_POST['B'] . ',2) - (4 * ' . $_POST['A'] . ' * ' . $_POST['C'] . ')'; $discriminant = Calculation::getInstance()->calculateFormula($discriminantFormula); $r1Formula = '=IMDIV(IMSUM(-' . $_POST['B'] . ',IMSQRT(' . $discriminant . ')),2 * ' . $_POST['A'] . ')'; $r2Formula = '=IF(' . $discriminant . '=0,"Only one root",IMDIV...

### Impact The cookie name could be used to set other fields of the cookie, resulting in an unexpected cookie value. For example, `serialize("userName=<script>alert('XSS3')</script>; Max-Age=2592000; a", value)` would result in `"userName=<script>alert('XSS3')</script>; Max-Age=2592000; a=test"`, setting `userName` cookie to `<script>` and ignoring `value`. A similar escape can be used for `path` and `domain`, which could be abused to alter other fields of the cookie. ### Patches Upgrade to 0.7.0, which updates the validation for `name`, `path`, and `domain`. ### Workarounds Avoid passing untrusted or arbitrary values for these fields, ensure they are set by the application instead of user input. ### References * https://github.com/jshttp/cookie/pull/167

### Summary The `HtmlGenerator` class is subject to potential cross-site scripting (XSS) attack through a parsed malformed Minecraft server MOTD. ### Context Minecraft server owners can set a so-called MOTD (Message of the Day) for their server that appears next to the server icon and below the server name on the multiplayer server list of a player's Minecraft client. The Minecraft server sends the MOTD in the `description` property of the [Status Response](https://wiki.vg/Server_List_Ping#Status_Response) packet. The [jgniecki/MinecraftMotdParser](https://github.com/jgniecki/MinecraftMotdParser) PHP library is able to parse the value of the `description` property, which can be either a string or an array of text components. By utilizing the aforementioned `HtmlGenerator` class, it is also able to transform the value into an HTML string that can be used to visualize the MOTD on a web page. ### Details The `HtmlGenerator` iterates through objects of `MotdItem` that are contained in an...
