CVE-2025-27772: Uptrain vulnerable to remote code execution via `/new_run` endpoint
UpTrain is an open-source platform to evaluate and improve generative AI applications. In version 0.7.1 and prior, the `/new_run` endpoint is vulnerable to remote code execution via the `checks` and `metadata` parameters. Any user that has access to UpTrain and a valid authentication method may be able to execute arbitrary code in the context of the host running UpTrain, which in most cases will be the docker container as suggested by the documentation. As of time of publication, no known patch is available.
Security readout for executives and security teams
Plain-English summary
UpTrain 0.7.1 and earlier can let an authenticated user run arbitrary code through the /new_run endpoint. Successful exploitation could compromise the confidentiality, integrity, and availability of the UpTrain host or its container. The supplied sources report no available patch.
Executive priority
Treat this as a high-priority exposure review. Immediately identify affected deployments, reduce access, and assess potential compromise. Prioritize externally reachable or multi-user instances. Because no patch was reported, risk reduction depends on isolation, access control, least privilege, monitoring, and continued vendor-guidance tracking.
Technical view
The /new_run endpoint improperly handles the checks and metadata parameters, enabling code injection classified as CWE-74. Exploitation is network-accessible, requires low privileges, needs no user interaction, and executes code in UpTrain's host context—typically its documented Docker container.
Likely exposure
Exposure exists where UpTrain 0.7.1 or earlier is deployed and an attacker can reach the service with valid authentication. Internet-accessible, broadly shared, or weakly controlled instances warrant the fastest review. The sources do not identify affected configurations beyond the stated version and access conditions.
Exploitation context
The CVSS 4.0 score is 7.4, and its vector records proof-of-concept exploit maturity (E:P). The CVE is not listed as KEV in the supplied bundle, and no cited evidence establishes active exploitation. Authentication is required, but any valid UpTrain user may represent a threat.
Researcher notes
The affected path is /new_run, with checks and metadata identified as dangerous inputs. The vulnerability boundary is authenticated access, not anonymous access. Host impact may initially be container-scoped, but actual consequences depend on container privileges, mounts, secrets, and network reach. The supplied evidence does not establish a patched release or active exploitation.
Mitigation direction
Inventory UpTrain deployments and identify every instance running version 0.7.1 or earlier.
Restrict UpTrain access to trusted users and tightly controlled networks.
Disable or isolate affected instances when access cannot be adequately restricted.
Review vendor and advisory guidance regularly; no known patch was available at publication.
Minimize container privileges, accessible secrets, mounted files, and network permissions.
Validation and detection
Confirm the installed UpTrain version using trusted deployment or package records.
Verify whether authenticated users can reach the /new_run endpoint.
Review authentication records and remove unnecessary, shared, or untrusted accounts.
Inspect application, container, and host logs for anomalous /new_run activity.
Check container mounts, secrets, privileges, and network access to determine potential impact.

The CVE wording references code or command execution, so execution technique review may help defensive triage. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
The affected technology mentions containers, so container-specific ATT&CK technique review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
