Descriptions

Grafana is an open source observability and data visualization platform. Versions prior to 9.1.8 and 8.5.14 are vulnerable to a bypass in the plugin signature verification. An attacker can convince a server admin to download and successfully run a malicious plugin even though unsigned plugins are not allowed. Versions 9.1.8 and 8.5.14 contain a patch for this issue. As a workaround, do not install plugins downloaded from untrusted sources.

Grafana es una plataforma de código abierto de observabilidad y visualización de datos. Las versiones anteriores a 9.1.8 y 8.5.14, son vulnerables a una omisión en la verificación de la firma del plugin. Un atacante puede convencer a un administrador del servidor para que descargue y ejecute con éxito un plugin malicioso a pesar de que los plugins sin firma no están permitidos. Las versiones 9.1.8 y 8.5.14 contienen un parche para este problema. Como mitigación, no instale plugins descargados de fuentes no confiables

A flaw was found in the Grafana web application, where it is possible to install plugins which are not digitally signed. An admin could install unsigned plugins, which may contain malicious code.
