CVE-2026-41458: CWE-362 Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') in owntone owntone-server
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.
AI Analysis
Technical Summary
CVE-2026-41458 is a race condition vulnerability (CWE-362) in OwnTone Server's DAAP login handler affecting versions 28.4.0 through 29.0. The vulnerability arises from improper synchronization when accessing the global DAAP session list, enabling unauthenticated attackers to trigger a denial of service by sending concurrent requests to the /login endpoint. This results in a server crash due to concurrent execution issues.
Potential Impact
An attacker can remotely cause a denial of service condition by crashing the OwnTone Server without authentication. This disrupts service availability for legitimate users. There are no indications of data compromise or privilege escalation from the provided information.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is currently documented. Until a patch is available, consider limiting access to the DAAP /login endpoint or implementing rate limiting to reduce the risk of exploitation.
