# CVE-2026-32327

> 9.1 CRITICAL

## Beschreibung

A bug in APR-util version 1.6.3 (and earlier) allows a stack recursion attack against any library consumer which parses XML from untrusted sources and uses the apr_xml_quote_elem() function.

Users are recommended to upgrade to version 1.6.4, which fixes this issue.
