CVE-2023-35053Network attack vector

Unauthenticated service interruption via Helpdesk forms

Published Jun 12, 2023 · Updated Jan 3, 2025

Uncontrolled resource consumption in JetBrains YouTrack before 2023.1.10518 allows remote attackers to interrupt service via Helpdesk forms. JetBrains identifies the locus as Helpdesk form processing but has not disclosed which request data consumes resources or how processing becomes unbounded. No authentication or user interaction is required; a crafted network request can make the service unavailable while leaving confidentiality and integrity unaffected.
