Name of the Vulnerable Software and Affected Versions: OWASP json-sanitizer versions prior to 1.2.2

Description: The issue arises when crafted input is processed, potentially leading to the output of invalid JSON or the throwing of an undeclared exception. This situation may result in a denial of service if the application is not equipped to handle such exceptions.
