High [CVE-2026-64849] Unauthenticated full-read SSRF in webhook delivery: _validate_webhook_url bypassed via unvalidated HTTP redirects (and DNS rebinding)
MLflow is an open source AI engineering platform for agents, large language models, and machine learning models. Prior to 3.15.0, the unauthenticated POST /api/2.0/mlflow/webhooks/{id}/test endpoint calls _validate_webhook_url() in mlflow/utils/validation.py only for the original URL while mlflow/webhooks/delivery.py follows redirects and re-resolves the hostname without pinning the validated address, allowing attackers to reach internal or cloud metadata services and receive response_status and response_body. This issue is fixed in version 3.15.0. A flaw was found in MLflow. An unauthenticated remote attacker can exploit a Server-Side Request Forgery (SSRF) vulnerability by sending a specially crafted request to the webhook test endpoint. This occurs because the system validates only the initial URL, but then follows unvalidated HTTP redirects, allowing the attacker to bypass security controls. Successful exploitation can lead to information disclosure, enabling access to internal or cloud metadata services and sensitive data. This flaw is in MLflow Tracking Server webhook delivery. An attacker who can reach the MLflow API can abuse POST /api/2.0/mlflow/webhooks/{id}/test to trigger SSRF and read upstream response bodies. Upstream rates this against the default unauthenticated mlflow server (PR:N).
High [CVE-2026-34398] Arbitrary Code Execution via malicious BIM project template
FreeCAD is a free and open-source multiplatform 3D parametric modeler. From 0.19 until 1.1.1, src/Mod/BIM/bimcommands/BimProjectManager.py in the BIM Project Manager Load Template flow passes attacker-controlled FCStd Meta property values for wpposition, wpu, wpv, and wpaxis directly to eval(), allowing arbitrary Python code execution when a user loads a malicious BIM project template. This issue is fixed in version 1.1.1. The BIM Project Manager's Load Template function does not properly validate certain properties within a project template. When a user opens this malicious template, the embedded code can be executed, potentially leading to arbitrary code execution on the user's system. This is an Important flaw in FreeCAD where loading a specially crafted BIM project template can lead to arbitrary code execution. The vulnerability requires user interaction to open a malicious file, but successful exploitation grants an attacker full control over the user's system, justifying its Important severity. Red Hat severity: Important — CVSS 7.8 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). Weakness: CWE-94.
