CVE-2023-26116: angular vulnerable to regular expression denial of service via the angular.copy() utility

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.

Root Cause Analysis

The vulnerability documentation explicitly identifies angular.copy() as the entry point for this ReDoS vulnerability. Multiple sources (GitHub Advisory, NVD, Snyk) consistently attribute the issue to an insecure regex pattern used within angular.copy()'s implementation. While the exact regex pattern and its specific location in the codebase aren't disclosed in the provided materials, the function's central role in the vulnerability is repeatedly confirmed across all advisories. The lack of commit diffs or patch information prevents more granular identification of the exact regex or helper functions involved, but the primary vulnerable function is clearly identified as angular.copy().
