Technical Details of CVE-2023-25572

This section provides more insights into the vulnerability, including its description, affected systems and versions, and the exploitation mechanism.

Vulnerability Description

The vulnerability stems from the

<RichTextField>

component in

react-admin

which outputs field values using

dangerouslySetInnerHTML

without proper client-side sanitization. This can lead to XSS attacks if the data is not sanitized server-side. Versions 3.19.12 and 4.7.6 have incorporated

DOMPurify

to escape HTML before outputting, addressing the issue.

Affected Systems and Versions
