Description

A flaw was found in fast-xml-parser. The XMLBuilder component does not properly escape specific sequences ("-->" in comments and "]]>" in CDATA sections) when constructing XML from JavaScript objects. This vulnerability allows an attacker to perform XML injection if user-controlled data is processed within comments or CDATA elements. Successful exploitation can lead to Cross-Site Scripting (XSS), SOAP injection, or unauthorized data manipulation.
