CWEhttps://cwe.mitre.org/data/definitions/1333.html

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.

Weakness

The product uses a regular expression with a worst-case computational complexity that is inefficient and possibly exponential.
