CVSS v3.1

Official Description

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).

Technical Analysis

CVE-2026-22679 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.

CISA has added CVE-2026-22679 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
