CVE-2023-36617

Summary

CVE-2023-36617 is a new vulnerability affecting the Ruby URI component before 0.12.2. This issue involves a ReDoS (Regular Expression Denial of Service) problem, where the URI parser mishandles invalid URLs containing specific characters. Consequently, there is an excessive increase in execution time when parsing strings to URI objects using rfc2396_parser.rb and rfc3986_parser.rb. Notably, this vulnerability arises due to an incomplete fix for a previous issue, CVE-2023-28755. To mitigate this risk, users are recommended to upgrade to version 0.12.2 or an earlier fixed version, 0.10.3.
