CVE-2026-71235 Detail
Received
This CVE record has recently been published to the CVE List and has been included within the NVD dataset. DescriptionMagistrala'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. Metrics
