Doc Text:	A flaw was found in jackrabbit-webdav. The WebDAV (Web Distributed Authoring and Versioning) server attaches a cached authenticated session when request header tokens—such as lock, transaction, or subscription identifiers—match, without verifying user credentials. An unauthenticated remote attacker can exploit this flaw to hijack existing user sessions, gaining unauthorized access to view or modify sensitive repository data.	Story Points:	---
