New Features #

Fixed CVE-2023-41834 #

Stateful Functions versions 3.1.0, 3.1.1 and 3.2.0 allowed HTTP header injection due to Improper Neutralization of CRLF Sequences. Attackers could potentially inject malicious content into the HTTP response that is sent to the user. This could include injecting a fake login form or other phishing content, or injecting malicious JavaScript code that can steal user credentials or perform other malicious actions on the user’s behalf.

Stateful Functions 3.3.0 has fixed this security vulnerability. More details can be found on the Security page.

Stateful Functions 3.3.0 runtime uses Flink 1.16.2 underneath. This means that Stateful Functions benefits from the latest improvements and stabilisations that went into Flink. For more information see Flink’s release announcement.
