CVE-2021-29622 – Arbitrary redirects under /new endpoint

https://notcve.org/view.php?id=CVE-2021-29622

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. • https://github.com/prometheus/prometheus/releases/tag/v2.26.1 https://github.com/prometheus/prometheus/releases/tag/v2.27.1 https://github.com/prometheus/prometheus/security/advisories/GHSA-vx57-7f4q-fpc7 https://access.redhat.com/security/cve/CVE-2021-29622 https://bugzilla.redhat.com/show_bug.cgi?id=1962718 • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
