CVE-2025-11958Network attack vector

Security Dashboard outage via malformed ignored-tasks request

Published Oct 22, 2025 · Updated Oct 22, 2025

Improper input validation in Devolutions Server 2025.2.15.0 and earlier allows remote authenticated users to disrupt the Security Dashboard. The ignored-tasks API accepts a crafted request without adequate input validation, but Devolutions has not disclosed the rejected field or failing operation. High-privilege access is required, and the documented consequence is limited to Security Dashboard unavailability rather than a full server outage.
