Version Details and Security Vulnerabilities

Versions of @hapi/hapi prior to 18.4.1 or 19.1.1 are vulnerable to Denial of Service. The CORS request handler has a vulnerability which will cause the function to throw a system error if the header contains some invalid values. If no unhandled exception handler is available, the application will exist, allowing an attacker to shut down services.

Recommendation

Upgrade to versions 18.4.1, 19.1.1 or later.

hoek versions prior to 8.5.1, and 9.x prior to 9.0.3 are vulnerable to prototype pollution in the clone function. If an object with the proto key is passed to clone() the key is converted to a prototype. This issue has been patched in version 9.0.3, and backported to 8.5.1.

Versions of @hapi/pez prior to 4.1.2 or 5.0.1 are vulnerable to Prototype Pollution. A multipart payload can be constructed in a way that one of the parts’ content can be set as the entire payload object’s prototype. If this prototype contains data, it may bypass other validation rules which enforce access and privacy. If this prototype evaluates to null, it can cause unhandled exceptions when the request payload is accessed.

Recommendation

Upgrade to versions 5.0.1 or later. There is a fix available for version 4.1.2, but it only available for direct download from the repository.

Versions of @hapi/content prior to 4.1.1 and 5.0.1 are vulnerable to Denial of Service. The Content-Encoding HTTP header parser has a vulnerability which will cause the function to throw a system error if the header contains some invalid values. Because hapi rethrows system errors (as opposed to catching expected application errors), the error is thrown all the way up the stack. If no unhandled exception handler is available, the application will exist, allowing an attacker to shut down services.

Recommendation

Upgrade to version 5.0.2. Versions 4.1.1 and 5.0.1 are fixed but only available for direct download through the repository.
