CVE-2026-19908

Data disclosure and configuration modification via unauthenticated daemon

Published Aug 14, 2026 · Updated Aug 14, 2026

Missing authentication in PAX Technology Q80 2.6.33.6690R XCB daemon allows attackers on an adjacent network to read data and alter configuration. The daemon accepts requests for sensitive-data and configuration functions without first establishing an authenticated identity. Adjacent-network access is sufficient; this flaw alone exposes data and configuration changes, while root code execution requires a vulnerability chain.
