CVE-2022-37262: 
JavaScript vulnerability analysis and mitigation

A Regular Expression Denial of Service (ReDoS) vulnerability was discovered in stealjs steal version 2.2.4. The vulnerability exists in main.js and can be triggered via the source and sourceWithComments variables (MITRE).

The vulnerability is caused by improper handling of regular expressions in the main.js file that process the source and sourceWithComments variables. This can lead to catastrophic backtracking in the regular expression engine (GitHub Issue).

When exploited, this vulnerability can cause excessive CPU usage through catastrophic backtracking in the regular expression engine, potentially leading to a denial of service condition where the application becomes unresponsive.

The vulnerability can be mitigated by implementing regular expression best practices to prevent catastrophic backtracking, such as avoiding nested quantifiers and properly limiting repetition patterns (GitHub Issue).
