{"id":"BIT-prometheus-2021-29622","summary":"Arbitrary redirects under /new endpoint","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.","aliases":["CVE-2021-29622","GHSA-vx57-7f4q-fpc7"],"modified":"2026-05-08T12:42:00.846364541Z","published":"2024-03-06T11:02:27.773Z","database_specific":{"cpes":["cpe:2.3:a:prometheus:prometheus:*:*:*:*:*:*:*:*","cpe:2.3:a:prometheus:prometheus:2.27.0:-:*:*:*:*:*:*","cpe:2.3:a:prometheus:prometheus:2.27.0:rc0:*:*:*:*:*:*"],"severity":"Medium"},"references":[{"type":"WEB","url":"https://github.com/prometheus/prometheus/releases/tag/v2.26.1"},{"type":"WEB","url":"https://github.com/prometheus/prometheus/releases/tag/v2.27.1"},{"type":"WEB","url":"https://github.com/prometheus/prometheus/security/advisories/GHSA-vx57-7f4q-fpc7"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-29622"}],"affected":[{"package":{"name":"prometheus","ecosystem":"Bitnami","purl":"pkg:bitnami/prometheus"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.23.0"},{"fixed":"2.26.1"},{"introduced":"2.27.0"},{"fixed":"2.27.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/prometheus/BIT-prometheus-2021-29622.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}],"schema_version":"1.7.3"}
