{"id":"AZL-6804","summary":"CVE-2021-29622 affecting package prometheus for versions less than 2.36.0-2","details":"Prometheus is an open-source monitoring system and time series database. In 2.23.0, Prometheus changed its default UI to the New ui. To ensure a seamless transition, the URL's prefixed by /new redirect to /. Due to a bug in the code, it is possible for an attacker to craft an URL that can redirect to any other URL, in the /new endpoint. If a user visits a prometheus server with a specially crafted address, they can be redirected to an arbitrary URL. The issue was patched in the 2.26.1 and 2.27.1 releases. In 2.28.0, the /new endpoint will be removed completely. The workaround is to disable access to /new via a reverse proxy in front of Prometheus.","modified":"2026-04-01T05:21:19.778997Z","published":"2021-05-19T20:15:07Z","upstream":["CVE-2021-29622"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-29622"}],"affected":[{"package":{"name":"prometheus","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/prometheus"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.36.0-2"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-6804.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
