CVE-2019-3826
Estado: ModificadaMedia (6.1)—
A stored, DOM based, cross-site scripting (XSS) flaw was found in Prometheus before version 2.7.1. An attacker could exploit this by convincing an authenticated user to visit a crafted URL on a Prometheus server, allowing for the execution and persistent storage of arbitrary scripts.
