{"apiVersion":"1.0","identifier":"CVE-2026-64849","description":"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.","publishedAt":"2026-08-17T22:17:23","lastModifiedAt":"2026-08-20T19:16:57","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-64849","cvssScore":9.3,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N","epssProbability":0.1641,"riskScore":2.3,"affectedProduct":"MLflow","affectedVersions":"<3.15.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-64849","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-64849","en":"https://www.redsauce.net/en/cves/CVE-2026-64849","fr":"https://www.redsauce.net/fr/cves/CVE-2026-64849","pt":"https://www.redsauce.net/pt/cves/CVE-2026-64849","de":"https://www.redsauce.net/de/cves/CVE-2026-64849","sk":"https://www.redsauce.net/sk/cves/CVE-2026-64849","el":"https://www.redsauce.net/el/cves/CVE-2026-64849"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-64849"}}
