Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Ibexa/fieldtype richtext, 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

### Impact This security advisory is a part of IBEXA-SA-2025-003, which resolves XSS vulnerabilities in several parts of the back office of Ibexa DXP. Back office access and varying levels of editing and management permissions are required to exploit these vulnerabilities. This typically means Editor or Administrator role, or similar. Injected XSS is persistent and can be reflected in the front office, possibly affecting end users. The fixes ensure XSS is escaped, and any existing injected XSS is rendered harmless. ### Patches - See "Patched versions". - https://github.com/ibexa/fieldtype-richtext/commit/4a4a170c7faa4807ae0f74c581481b835bab3caf ### Workarounds None.
