CVE-2026-54602 labring CVE debrief

Who should care

Users of FastGPT, especially those with multiple teams, should be aware of this vulnerability and ensure they are running version 4.15.0 or later to prevent unauthorized access to sensitive information. This includes operators, platform administrators, vulnerability management teams, and security teams.

Technical summary

The vulnerability exists in the GET /api/core/ai/record/getRecord endpoint of FastGPT, a knowledge-based AI application platform. Prior to version 4.15.0, this endpoint authenticates the caller but loads LLM request and response traces only by requestId without team scoping. This allows any authenticated user to access another team's data if the requestId is known. The issue is fixed in version 4.15.0 of FastGPT. Affected product deployments should be reviewed for exposure, and owners should plan for vendor-supported updates or mitigations through normal change control. Compensating controls should be reviewed for exposed systems while remediation is scheduled and verified.

Defensive priority

High priority should be given to upgrading to FastGPT version 4.15.0 or later, reviewing and restricting access to sensitive information, and monitoring for suspicious activity. Compensating controls should be reviewed for exposed systems while remediation is scheduled and verified. Relevant monitoring, detection, and logs should be checked for exposed assets that need extra review. Exceptions should be tracked, and remediated assets should be retested and closed only after evidence is documented. Asset inventory and source tracking are also recommended. Rollback/change windows should be considered if necessary.

Recommended defensive actions

• Upgrade to FastGPT version 4.15.0 or later
• Review and restrict access to sensitive information
• Monitor for suspicious activity
• 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
