| Name | CVE-2021-29622 |
| Description | 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. |

"Fixed" because the 2.15.2+ds-1 upload disabled codewise the functionality
(due to lack of React support in Debian) in 01-Do_not_embed_blobs.patch.
The vulnerability itself is introduced with 2.23.0 upstream.
See https://bugs.debian.org/988804 for details.
