Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-80: Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS), where the product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as "<", ">", and "&" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages. In Withdrawn Advisory, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## Withdrawn Advisory This advisory has been withdrawn because the vendor reports that some HTML formatting (such as with an H1 element) is allowed, but there is backend sanitization such that the reporter's mentioned "injecting malicious scripts" would not occur. ## Original Advisory An HTML injection vulnerability in the Edit Content Layout module of Kirby CMS v4.1.0 allows attackers to execute arbitrary code via a crafted payload.
