CVE-2023-28755: Input Validation

First published: Tue Mar 21 2023(Updated: )

A flaw was found in the rubygem URI. The URI parser mishandles invalid URLs that have specific characters, which causes an increase in execution time parsing strings to URI objects. This may result in a regular expression denial of service (ReDoS).
