SilverStripe through 4.6.0-rc1 has an XXE Vulnerability in CSSContentParser. A developer utility meant for parsing HTML within unit tests can be vulnerable to XML External Entity (XXE) attacks. When this developer utility is misused for purposes involving external or user submitted data in custom project code, it can lead to vulnerabilities such as XSS on HTML output rendered through this custom code. This is now mitigated by disabling external entities during parsing. (The correct CVE ID year is 2020 [CVE-2020-25817, not CVE-2021-25817]).

Silverstripe Framework is a PHP framework which powers the Silverstripe CMS. In some cases, form messages can contain HTML markup. This is an intentional feature, allowing links and other relevant HTML markup for the given message. Some form messages include content that the user can provide. There are scenarios in the CMS where that content doesn't get correctly sanitised prior to being included in the form message, resulting in an XSS vulnerability. This issue has been addressed in silverstripe/framework version 5.3.8 and users are advised to upgrade. There are no known workarounds for this vulnerability.

There is XSS in SilverStripe CMS before 3.4.4 and 3.5.x before 3.5.2. The attack vector is a page name. An example payload is a crafted JavaScript event handler within a malformed SVG element.

Silverstripe framework is the PHP framework forming the base for the Silverstripe CMS. In affected versions a bad actor with access to edit content in the CMS could add send a specifically crafted encoded payload to the server, which could be used to inject a JavaScript payload on the front end of the site. The payload would be sanitised on the client-side, but server-side sanitisation doesn't catch it. The server-side sanitisation logic has been updated to sanitise against this type of attack in version 5.2.16. All users are advised to upgrade. There are no known workarounds for this vulnerability.

The payload would be sanitized on the client-side, but server-side sanitization doesn't catch it. The server-side sanitization logic has been updated to sanitize against this attack. This vulnerability is fixed in 5.3.23.

Silverstripe Elemental extends a page type to swap the content area for a list of manageable elements to compose a page out of rather than a single text field. An elemental block can include an XSS payload, which can be executed when viewing the "Content blocks in use" report. The vulnerability is specific to that report and is a result of failure to cast input prior to including it in the grid field. This vulnerability is fixed in 5.3.12.

The Elementor Header & Footer Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the url attribute within the plugin's Site Title widget in all versions up to, and including, 1.6.35 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Label Studio is an a popular open source data labeling tool. Versions prior to 1.9.2 have a cross-site scripting (XSS) vulnerability that could be exploited when an authenticated user uploads a crafted image file for their avatar that gets rendered as a HTML file on the website. Executing arbitrary JavaScript could result in an attacker performing malicious actions on Label Studio users if they visit the crafted avatar image. For an example, an attacker can craft a JavaScript payload that adds a new Django Super Administrator user if a Django administrator visits the image. The file `users/functions.py` lines 18-49 show that the only verification check is that the file is an image by extracting the dimensions from the file. Label Studio serves avatar images using Django's built-in `serve` view, which is not secure for production use according to Django's documentation. The issue with the Django `serve` view is that it determines the `Content-Type` of the response by the file extension in the URL path. Therefore, an attacker can upload an image that contains malicious HTML code and name the file with a `.html` extension to be rendered as a HTML page. The only file extension validation is performed on the client-side, which can be easily bypassed. Version 1.9.2 fixes this issue. Other remediation strategies include validating the file extension on the server side, not in client-side code; removing the use of Django's `serve` view and implement a secure controller for viewing uploaded avatar images; saving file content in the database rather than on the filesystem to mitigate against other file related vulnerabilities; and avoiding trusting user controlled inputs.
