CVE-2026-93985Public exploitNetwork attack vector

Worker code execution via computed constructor access

Published Sep 19, 2026 · Updated Sep 19, 2026

Code injection in OpenPanel through commit bad75bdd allows remote authenticated users to execute arbitrary code in the worker process. The webhook template validator skips allowlist checks for computed member calls, while execution later compiles the stored template with the host Function constructor. Project write access and delivery of a matching notification are required; successful exploitation grants the worker process's privileges and access to its service credentials.
