CVE-2026-115657 KNIME CVE debrief

Who should care

Defenders and administrators of KNIME Analytics Platform instances used as executors in KNIME Server or KNIME Business Hub should assess exposure and prioritize remediation. This includes reviewing system configurations, securing log files, and monitoring for potential credential misuse. Additionally, defenders should verify and remediate affected instances, especially for versions before 5.8.4, and implement additional security measures to prevent similar

Why it matters

Defenders should care about CVE-2026-115657 because it involves the logging of proxy credentials in KNIME Analytics Platform when used as an executor, potentially leading to credential theft and unauthorized proxy use. Relevant roles include administrators and defenders of KNIME Analytics Platform instances in KNIME Server or KNIME Business Hub environments. Supported consequences include potential credential exposure and unauthorized proxy usage. Evidence limits indicate that specific version information and exploitation details require verification from official sources.

• Potential credential theft from log files
• Possible unauthorized proxy usage
• Required verification of affected versions and instances
• Necessary remediation to prevent credential exposure

Technical summary

KNIME Analytics Platform LTS versions before 5.8.4 log configured proxy credentials during startup when used as an executor in KNIME Server or KNIME Business Hub. An attacker with access to log files can steal these credentials and use the proxy as the user who configured the proxy settings. The issue has been fixed in LTS versions 5.8.4 and 5.12.0 and later. It is essential to verify and remediate affected instances, especially for versions before 5.8.4, and to review and secure log file access to prevent potential credential misuse.

Defensive priority

Defenders should prioritize verifying and remediating KNIME Analytics Platform instances used as executors in KNIME Server or KNIME Business Hub, especially for versions before 5.8.4.

Recommended defensive actions

• Verify KNIME Analytics Platform versions used as executors in KNIME Server or KNIME Business Hub
• Remediate to version 5.8.4 or later
• Review and secure log file access
• Monitor for potential credential misuse
• Perform a thorough review of the system configuration and proxy settings
• Check for any unauthorized access or suspicious activity
• Implement additional security measures to prevent similar vulnerabilities in the future

Evidence notes
