CVE-2025-27772 uptrain-ai CVE debrief

Who should care

UpTrain users, administrators, and security teams should assess their exposure and take necessary precautions to mitigate potential risks. This includes verifying deployment contexts, limiting access to the `/new_run` endpoint, and monitoring for potential exploitation attempts.

Why it matters

CVE-2025-27772 is a high-severity vulnerability in UpTrain that allows remote code execution. UpTrain users and administrators should assess their exposure and take necessary precautions to mitigate potential risks.

• Potential remote code execution in the context of the host running UpTrain
• Arbitrary code execution may lead to unauthorized access and data breaches
• Successful exploitation may require user authentication
• Verification of UpTrain version and patch status is necessary

Technical summary

The vulnerability is caused by insufficient input validation in the `/new_run` endpoint's `checks` and `metadata` parameters. This allows an attacker to execute arbitrary code in the context of the host running UpTrain, typically a Docker container. The vulnerability has a CVSS score of 7.4 and is classified as HIGH severity. UpTrain users and administrators should assess their exposure and take necessary precautions to mitigate potential risks. This includes verifying deployment contexts, limiting access to the `/new_run` endpoint, and monitoring for potential exploitation attempts. As of the publication date, no known patch is available.

Defensive priority

Immediate attention is required to assess exposure and mitigate potential risks. UpTrain users should verify their deployment context and consider compensating controls until a patch is available.

Recommended defensive actions

• Assess exposure by verifying UpTrain deployment and user access
• Implement compensating controls to limit access to the `/new_run` endpoint
• Monitor for potential exploitation attempts
• Consider upgrading to a patched version once available
• Review compensating controls for exposed systems while remediation is scheduled and verified
• 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
