Description
A flaw in the cross-site request forgery (CSRF) prevention of KNIME Business Hub prior to version 1.19.0 allows an authenticated attacker to perform a CSRF attack with passive user interaction. This means the state of a resource could be changed without the user noticing. As a workaround, an API gateway for firewall in front of KNIME Business Hub could remove the X-Forwaded-For header from all incoming requests.
