Title
Improper Origin Validation in mlflow/mlflow
Summary
In MLflow version 3.9.0, the MLflow Assistant feature introduced improper origin validation in its /ajax-api endpoints. This vulnerability allows a remote attacker to exploit cross-origin requests from a malicious webpage to interact with the MLflow Assistant running on a victim's local machine. By bypassing the loopback-only restriction, the attacker can modify the Assistant's configuration to enable full access, which in turn allows the execution of arbitrary commands via the Claude Code sub-agent. This issue is resolved in version 3.10.0.

Improper origin validation in the MLflow Assistant\u0027s /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\u0027s local machine, bypassing loopback-only restrictions. Consequently, an attacker can modify the Assistant\u0027s configuration to gain full access, leading to the execution of arbitrary commands via the Claude Code sub-agent.\"}], \"problemTypes\": [{\"descriptions\": [{\"lang\": \"en\", \"type\": \"CWE\", \"cweId\": \"CWE-940\", \"description\": \"Improper Verification of Source of a Communication Channel\"}]}], \"providerMetadata\": {\"orgId\": \"0b0ca135-0b70-47e7-9f44-1890c2a1c46c\", \"shortName\": \"redhat-SADP\", \"dateUpdated\": \"2026-06-27T05:17:23.313Z\"}}, {\"title\": \"CISA ADP Vulnrichment\", \"metrics\": [{\"other\": {\"type\": \"ssvc\", \"content\": {\"id\": \"CVE-2026-2611\", \"role\": \"CISA Coordinator\", \"options\": [{\"Exploitation\": \"poc\"}, {\"Automatable\": \"no\"}, {\"Technical Impact\": \"total\"}], \"version\": \"2.0.3\", \"timestamp\": \"2026-05-19T13:26:07.361461Z\"}}}], \"references\": [{\"url\": \"https://huntr.com/bounties/8462addd-b464-4a84-b6a2-5529604e6e5a\", \"tags\": [\"exploit\"]}], \"providerMetadata\": {\"orgId\": \"134c704f-9b21-4f2e-91b3-4a467353bcc0\", \"shortName\": \"CISA-ADP\", \"dateUpdated\": \"2026-05-19T13:26:28.318Z\"}}], \"cna\": {\"title\": \"Improper Origin Validation in mlflow/mlflow\", \"source\": {\"advisory\": \"8462addd-b464-4a84-b6a2-5529604e6e5a\", \"discovery\": \"EXTERNAL\"}, \"metrics\": [{\"cvssV3_0\": {\"scope\": \"CHANGED\", \"version\": \"3.0\", \"baseScore\": 9.6, \"attackVector\": \"NETWORK\", \"baseSeverity\": \"CRITICAL\", \"vectorString\": \"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H\", \"integrityImpact\": \"HIGH\", \"userInteraction\": \"REQUIRED\", \"attackComplexity\": \"LOW\", \"availabilityImpact\": \"HIGH\", \"privilegesRequired\": \"NONE\", \"confidentialityImpact\": \"HIGH\"}}], \"affected\": [{\"vendor\": \"mlflow\", \"product\": \"mlflow/mlflow\", \"versions\": [{\"status\": \"affected\", \"version\": \"unspecified\", \"lessThan\": \"3.10.0\", \"versionType\": \"custom\"}]}], \"references\": [{\"url\": \"https://huntr.com/bounties/8462addd-b464-4a84-b6a2-5529604e6e5a\"}, {\"url\": \"https://github.com/mlflow/mlflow/commit/8f9c8a53af90842944101eb8b7d60706822c81bc\"}], \"descriptions\": [{\"lang\": \"en\", \"value\": \"In MLflow version 3.9.0, the MLflow Assistant feature introduced improper origin validation in its /ajax-api endpoints.
