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 1.2.21 are vulnerable to Regular Expression Denial of Service (ReDoS) via the angular.copy() utility function due to the usage of an insecure regular expression. Exploiting this vulnerability is possible by a large carefully-crafted input, which can result in catastrophic backtracking.
