Uploaded SVG files could contain scripts and if rendered inline those scripts could run allowing XSS attacks.

A specially crafted URL may be constructed which can inject an XSS payload that is triggered by using some module actions.

A cross-site scripting (XSS) vulnerability exists in Grafana caused by combining a client path traversal and open redirect. This allows attackers to redirect users to a website that hosts a frontend plugin that will execute arbitrary JavaScript. This vulnerability does not require editor permissions and if anonymous access is enabled, the XSS will work. If the Grafana Image Renderer plugin is installed, it is possible to exploit the open redirect to achieve a full read SSRF. The default Content-Security-Policy (CSP) in Grafana will block the XSS though the `connect-src` directive.

The ns_backup extension through 13.0.0 for TYPO3 allows XSS.

Cross-site scripting (XSS) vulnerability in the [clickstorm] SEO (cs_seo) TYPO3 extension allows backend users to execute arbitrary script via the JSON-LD output.

### Impact Rendering `{{ attributes }}` or using any method that returns a `ComponentAttributes` instance (e.g. `only()`, `defaults()`, `without()`) ouputs attribute values directly without escaping. If these values are unsafe (e.g. contain user input), this can lead to HTML attribute injection and XSS vulnerabilities. ### Patches The issue is fixed in version `2.25.1` of `symfony/ux-twig-component` by using Twig's `EscaperRuntime` to properly escape HTML attributes in `ComponentAttributes`. If you use `symfony/ux-live-component`, you must also update it to `2.25.1` to benefit from the fix, as it reuses the `ComponentAttributes` class internally. ### Workarounds Until you can upgrade, avoid rendering `{{ attributes }}` or derived objects directly if it may contain untrusted values. Instead, use `{{ attributes.render('name') }}` for safe output of individual attributes. ### References GitHub repository: [symfony/ux](https://github.com/symfony/ux)

A cyber-espionage campaign is targeting Ukrainian government entities with a series of sophisticated spear-phishing attacks that exploit XSS vulnerabilities.

### LibreNMS v25.4.0 suffers from Stored Cross-Site Scripting (XSS) Vulnerability in the 'group name' parameter of the 'http://localhost/poller/groups' form. This vulnerability allows attackers to inject malicious scripts into web pages viewed by other users. ## ---------------------------------POC----------------------------- Before Setting: Enable 'distributed_poller' in http://localhost/settings/poller/distributed 1. Attacker creates a new poller group and injects the payload in the 'group name' parameter ``` payload: <script>alert('XSS')</script> ``` 2. Victim navigates to the 'http://localhost/addhost' to add a new host 3. The payload is executed code sink: https://github.com/librenms/librenms/blob/25.4.0/includes/html/pages/addhost.inc.php#L284
