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.

Impact

A flaw in the CSRF prevention of KNIME Business Hub allows an authenticated attacker to bypass standard protection by forging an X-Forwarded-Host header. This enables state changes to resources without the user's knowledge, effectively permitting unauthorized modifications of data or configurations. The weakness is classified as CWE-352, indicating a cross‑site request forgery vulnerability.

Affected Systems

All KNIME Business Hub installations running any version before 1.19.0 are affected. The issue appears in the versions controlled by KNIME:KNIME Business Hub prior to the 1.19.0 release. No additional vendor or version details are available beyond the stated cutoff.

Risk and Exploitability

The vulnerability carries a CVSS score of 5.3, indicating moderate severity. EPSS data is currently unavailable, and the vulnerability is not listed in the CISA KEV catalog, suggesting no widespread exploitation has been confirmed. The likely attack path requires an attacker to be authenticated to the hub and to supply a request that contains a forged X-Forwarded-Host header, with the victim’s browser performing a passive request. Because the flaw is exploitable via normal web traffic, care should be taken especially in environments where the hub is exposed to untrusted networks.
