NVD Description

Note: Versions mentioned in the description apply only to the upstream grafana-loki package and not the grafana-loki package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

Versions of the package angular from 1.4.9 are vulnerable to Regular Expression Denial of Service (ReDoS) via the <input type="url"> element due to the usage of an insecure regular expression in the input[url] functionality. Exploiting this vulnerability is possible by a large carefully-crafted input, which can result in catastrophic backtracking.
