{"id":"CVE-2026-44725","state":"PUBLISHED","title":"EMQX: Stale plugins allow grants amplify a compromised admin/API key to remote code execution","description":"EMQX is a scalable and reliable MQTT broker for AI, IoT, IIoT, and connected vehicles. Prior to versions 5.8.11, 5.9.3, 5.10.4, 6.0.3, 6.1.2, and 6.2.1, the plugin-install REST API and dashboard upload accepted stale grants created with emqx ctl plugins allow because there was no five-minute grant lifetime or SHA-256 package binding. An attacker with a compromised dashboard administrator credential or API key with plugin-install permission who finds a stale allowed name and version can upload attacker-controlled bytes under the allowed .tar.gz filename through POST /api/v5/plugins/install or the dashboard plugin upload. The broker then installs and runs attacker-controlled Erlang code with the privileges of the EMQX process.
