CVE-2026-24816Network attack vector

Unauthenticated service interruption

Published Jan 27, 2026 · Updated Jan 27, 2026

Infinite loop in ChangeDomainAction.java in Datavane TIS before 4.3.0 allows remote attackers to interrupt the TIS Console service. The CNA identifies the affected action module but does not disclose the input, loop, or unreachable exit condition that triggers the flaw. Network access without authentication is sufficient, but published materials do not state whether exploitation causes a hang, resource exhaustion, or another observable failure.
