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 the OwnTone Server's DAAP login handler. The issue arises from improper synchronization when accessing the global DAAP session list, allowing unauthenticated remote attackers to trigger a denial of service by sending concurrent requests to the /login endpoint. This affects OwnTone Server versions 28.4 through 29.0, with a CVSS 4.0 score of 8.2 indicating high severity. No vendor advisory or patch information is currently available.
Potential Impact
An unauthenticated attacker can remotely cause a denial of service by crashing the OwnTone Server through concurrent request flooding of the DAAP /login endpoint. This disrupts service availability but does not indicate data compromise or privilege escalation based on the provided information.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, consider limiting access to the DAAP /login endpoint or implementing rate limiting to reduce the risk of exploitation.
