CVE-2026-115454 KNIME CVE debrief

Who should care

Defenders responsible for KNIME Business Hub deployments should assess exposure and prioritize verification and remediation. This includes reviewing the official advisory and CVE record to validate affected scope, severity, and vendor guidance, and planning for vendor-supported updates or mitigations through normal change control where exposure is confirmed. Additionally, defenders should monitor workflow execution functionality for intermittent unavailabi

Why it matters

Excessive resource allocation in KNIME Business Hub can lead to workflow execution unavailability, requiring defenders to verify and remediate vulnerable deployments.

• Verify and upgrade to version 1.19.0 or later to prevent resource exhaustion
• Monitor workflow execution functionality for intermittent unavailability
• Implement resource allocation limits and monitoring for KNIME Business Hub

Technical summary

The excessive resource allocation issue in KNIME Business Hub prior to version 1.19.0 allows an authenticated attacker to exhaust server resources, leading to intermittent unavailability of workflow execution functionality. This issue arises from the remote workflow editing capabilities of KNIME Business Hub, which can be exploited by an attacker to cause resource exhaustion. To prevent this, defenders should prioritize verifying and upgrading to version 1.19.0 or later, and implement resource allocation limits and monitoring for KNIME Business Hub.

Defensive priority

Defenders should prioritize verifying and upgrading to version 1.19.0 or later to prevent resource exhaustion.

Recommended defensive actions

• Verify KNIME Business Hub version and upgrade to 1.19.0 or later if necessary
• Monitor workflow execution functionality for intermittent unavailability
• Implement resource allocation limits and monitoring for KNIME Business Hub
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
