Inefficient Regular Expression Complexity
All versions of the package angular 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.
CWE-1333 - Inefficient Regular Expression Complexity
The product uses a regular expression with an inefficient, possibly exponential worst-case computational complexity that consumes excessive CPU cycles.
