### Summary `\PhpOffice\PhpSpreadsheet\Writer\Html` does not sanitize "javascript:" URLs from hyperlink `href` attributes, resulting in a Cross-Site Scripting vulnerability. ### PoC Example target script: ``` <?php require 'vendor/autoload.php'; $reader = \PhpOffice\PhpSpreadsheet\IOFactory::createReader("Xlsx"); $spreadsheet = $reader->load(__DIR__ . '/book.xlsx'); $writer = new \PhpOffice\PhpSpreadsheet\Writer\Html($spreadsheet); print($writer->generateHTMLAll()); ``` Save this file in the same directory: [book.xlsx](https://github.com/PHPOffice/PhpSpreadsheet/files/15099763/book.xlsx) Open index.php in a web browser and click on both links. The first demonstrates the vulnerability in a regular hyperlink and the second in a HYPERLINK() formula.

### Summary Event log data is not properly sanitized leading to stored Cross-Site Scripting (XSS) vulnerability. ### Details - file: https://github.com/saltcorn/saltcorn/blob/v1.0.0-beta.13/packages/server/routes/eventlog.js#L445 ```js router.get( "/:id", isAdmin, error_catcher(async (req, res) => { const { id } = req.params; const ev = await EventLog.findOneWithUser(id); send_events_page({ [...] contents: { type: "card", contents: [...] ) + div( { class: "eventpayload" }, ev.payload ? pre(JSON.stringify(ev.payload, null, 2)) : "" //<--- ), }, }); }) ``` ### PoC The following PoC demonstrates how a non-admin user with permission to read/write on a table can inject malicious javascript code that will be executed in the event log admin panel if event logs are enabled. To demonstrate this issue, we need to prepare some components. The following steps should be ...

### 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...
