CVE-2026-71235Network attack vector

Authenticated server-side code execution via unrestricted scripts

Published Aug 5, 2026 · Updated Aug 5, 2026

Code injection in Magistrala Rules Engine allows remote authenticated users to read and write files via crafted Go or Lua rules. The Go engine passes scripts to Yaegi with stdlib.Symbols after only regex-blocking goroutines and panic(), while the Lua engine performs no validation and preloads database, file, HTTP, and path libraries. Rule-creation access is sufficient; scripts run when IoT messages arrive and can expose environment variables, modify files, query databases, or issue SSRF requests to internal microservices.
