CVE-2026-2611
Description
A flaw was found in MLflow. Improper origin validation in the MLflow Assistant's /ajax-api endpoints allows a remote attacker to exploit cross-origin requests from a malicious webpage. This enables interaction with the MLflow Assistant running on a victim's local machine, bypassing loopback-only restrictions. Consequently, an attacker can modify the Assistant's configuration to gain full access, leading to the execution of arbitrary commands via the Claude Code sub-agent.
Statement
No Red Hat products ship the affected version of mlflow.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
