There is no fixed version for Debian:11 dogtag-pki.

NVD Description

Note: Versions mentioned in the description apply only to the upstream dogtag-pki package and not the dogtag-pki package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

A flaw was found in Dogtag PKI's ACME responder where the web.xml security constraints use exact URL pattern matching for admin-only enable/disable endpoints. By appending a trailing slash to the URL, an unauthenticated attacker can bypass the Tomcat authentication constraint while RESTEasy still routes the request to the handler, allowing unauthorized toggling of the ACME service state including persistent denial of service.
