CVE-2026-19932Public exploitNetwork attack vector

Unauthenticated code execution via GroovyShell.evaluate

Published Aug 16, 2026 · Updated Aug 16, 2026

Code injection in Notice System Management 2.0 allows remote attackers to execute arbitrary Groovy code through the /execute endpoint. NoticeController sends the request's code parameter directly to GroovyShell.evaluate without sanitization, an allowlist, or a sandbox. The route contains no authorization check and the published request supplies no credentials, so operating-system commands run with the server process's privileges.
