Weaver (Fanwei) E-cology 10.0 versions prior to 20260312 contain an unauthenticated remote code execution vulnerability in the /papi/esearch/data/devops/dubboApi/debug/method endpoint that allows attackers to execute arbitrary commands by invoking exposed debug functionality. Attackers can craft POST requests with attacker-controlled interfaceName and methodName parameters to reach command-execution helpers and achieve arbitrary command execution on the system. Exploitation evidence was first observed by the Shadowserver Foundation on 2026-03-31 (UTC).
