Contributor-level service disruption

Published Mar 21, 2024 · Updated Apr 28, 2026

Uncontrolled resource consumption in David Artiss Code Embed 2.3.6 and earlier allows remote authenticated users to disrupt WordPress sites. Public advisories do not identify the affected function, crafted input, or resource whose unbounded consumption causes the denial of service. Contributor-level access is required, and exploitation interrupts site availability without reported data access or modification.
