NVD Description

Note: Versions mentioned in the description apply only to the upstream satellite/iop-host-inventory-frontend-rhel9 package and not the satellite/iop-host-inventory-frontend-rhel9 package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

fast-xml-parser allows users to validate XML, parse XML to JS object, or build XML from JS object without C/C++ based libraries and no callback. From 4.1.3to before 5.3.5, a dot (.) in a DOCTYPE entity name is treated as a regex wildcard during entity replacement, allowing an attacker to shadow built-in XML entities (<, >, &, ", ') with arbitrary values. This bypasses entity encoding and leads to XSS when parsed output is rendered. This vulnerability is fixed in 5.3.5.
