Authenticated users with backup permissions can read arbitrary files within the webroot via path traversal in the Backup addon's file export functionality.

A stored cross-site scripting (XSS) vulnerability in the module management component in REDAXO CMS 5.20.0 allows remote users to inject arbitrary web script or HTML via the Output code field in modules. The payload is executed when a user views or edits an article by adding slice that uses the compromised module.

A reflected Cross-Site Scripting (XSS) vulnerability exists in the Mediapool view where the request parameter args[types] is rendered into an info banner without HTML-escaping. This allows arbitrary JavaScript execution in the backend context when an authenticated user visits a crafted link while logged in.

A Remote Code Execution (RCE) vulnerability in the template management component in REDAXO CMS 5.20.0 allows remote authenticated administrators to execute arbitrary operating system commands by injecting PHP code into an active template. The payload is executed when visitors access frontend pages using the compromised template.

Reflected cross-site scripting (XSS) is a type of web vulnerability that occurs when a web application fails to properly sanitize user input, allowing an attacker to inject malicious code into the application's response to a user's request. When the user's browser receives the response, the malicious code is executed, potentially allowing the attacker to steal sensitive information or take control of the user's account.

An arbitrary file upload vulnerability was identified in the redaxo. This flaw permits users to upload malicious files, which can lead to JavaScript code execution and distribute malware.
