CVE-2026-92414Network attack vectorHinoki check available

Unauthenticated session hijack via WebDAV token reuse

Published Oct 7, 2026 · Updated Oct 7, 2026

Session reuse in Apache Jackrabbit 2.20.0 through 2.20.17 allows remote attackers to hijack authenticated WebDAV sessions. The WebDAV server attaches a cached authenticated session when a Lock-Token, TransactionId, SubscriptionId, or If header contains a matching token, without checking the requester's credentials. The flaw also affects 2.22.0 through 2.22.4 and 2.23.0 through 2.23.5; exploitation requires a reachable WebDAV endpoint and a matching token, and grants access within the matched user's session.
