Doc Text:
A flaw was found in Magistrala's Rules Engine. An authenticated low-privileged user can exploit this vulnerability by creating rules with embedded Go or Lua scripts. These scripts are executed server-side without sufficient validation, allowing for arbitrary file read and write operations, access to internal databases, and Server-Side Request Forgery (SSRF) against internal microservices. This could lead to significant data compromise and unauthorized system access.

Description OSIDB Bzimport 2026-08-05 12:07:27 UTC 
Magistrala's Rules Engine allows authenticated users to create rules with embedded Go or Lua scripts executed server-side when IoT messages arrive. The Go script engine (re/golang.go) runs scripts through the Yaegi interpreter with stdlib.Symbols, exposing the full Go standard library (including os and net/http) with validation limited to a regex blocking goroutines and panic() calls; dangerous functions such as os.ReadFile, os.WriteFile, os.Remove, and os.Environ remain fully accessible. The Lua script engine (re/lua.go) performs no input validation at all and preloads dangerous libraries: db (arbitrary database access), ioutil (file I/O), an HTTP client (SSRF), and filepath (traversal). An authenticated low-privileged user can achieve arbitrary file read/write, environment variable leakage, database access, and SSRF against internal microservices.
