CVE-2026-41458

Description

OwnTone Server versions 28.4 through 29.0 contain a race condition vulnerability in the DAAP login handler that allows unauthenticated attackers to crash the server by exploiting unsynchronized access to the global DAAP session list. Attackers can flood the DAAP /login endpoint with concurrent requests to trigger a remote denial of service condition without requiring authentication.
