CVE-2026-75415 AntFlow CVE debrief

Who should care

Organizations using AntFlow V2.0.0, security teams responsible for identity verification mechanisms, administrators of affected systems, and operators of potentially exposed platforms should be aware of this vulnerability and take necessary precautions. This includes verifying inventory, applying vendor remediation, and monitoring for suspicious activity related to identity verification mechanisms. The whoShouldCare section provides impact context for affected operators, platforms, vulnerability management, and security teams.

Technical summary

The JiMuMDCCommonsRequestLoggingFilter.java component in AntFlow V2.0.0 retrieves the userid from the request header as part of its identity verification mechanism. This implementation allows attackers to forge any user identity credential information, potentially leading to sensitive information leakage. The vulnerability has been classified as HIGH with a CVSS score of 7.5. Affected product deployments should be verified, and owners should be assigned for follow-up. The technical summary provides context on the affected product, defensive impact, and source-grounded technical framing.

Defensive priority

Organizations using AntFlow V2.0.0 should prioritize verifying their inventory and applying vendor remediation to prevent potential sensitive information leakage.

Recommended defensive actions

• Verify inventory of AntFlow V2.0.0 installations
• Apply vendor remediation when available
• Monitor for suspicious activity related to identity verification mechanisms
• 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
