    messageformat is an Intl.MessageFormat / Unicode MessageFormat 2 parser, runtime and polyfill

    Affected versions of this package are vulnerable to Prototype Pollution via improper handling of message key paths containing special characters in the process when processing nested message keys. An attacker can modify the JavaScript Object prototype by injecting properties into the global object prototype through specially crafted message input, potentially causing denial of service or other unintended behaviors.
