{"id":"CVE-2026-0596","state":"PUBLISHED","title":"Command Injection in mlflow/mlflow","description":"A command injection vulnerability exists in mlflow/mlflow when serving a model with `enable_mlserver=True`. The `model_uri` is embedded directly into a shell command executed via `bash -c` without proper sanitization. If the `model_uri` contains shell metacharacters, such as `$()` or backticks, it allows for command substitution and execution of attacker-controlled commands. This vulnerability affects the latest version of mlflow/mlflow and can lead to privilege escalation if a higher-privileged service serves models from a directory writable by lower-privileged users.","publishedAt":"2026-03-31T14:25:27.716Z","updatedAt":"2026-04-01T03:55:35.518Z","severity":{"score":9.6,"label":"Critical","version":"3.0","vector":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","source":"@huntr_ai"},"assigner":"@huntr_ai","products":["mlflow mlflow/mlflow"],"affected":[{"vendor":"mlflow","product":"mlflow/mlflow","versions":[{"version":"unspecified","status":"affected","lessThanOrEqual":"latest","versionType":"custom"}]}],"references":["https://huntr.com/bounties/2e905add-f9f5-4309-a3db-b17de5981285"],"weaknesses":["CWE-78"],"ingestedAt":"2026-10-29T20:10:13.529Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/0xxx/CVE-2026-0596.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-0596","state":"PUBLISHED","datePublished":"2026-03-31T14:25:27.716Z","dateUpdated":"2026-04-01T03:55:35.518Z","assignerShortName":"@huntr_ai","assignerOrgId":"c09c270a-b464-47c1-9133-acb35b22c19a","dateReserved":"2026-01-05T03:58:44.787Z"},"containers":{"cna":{"title":"Command Injection in mlflow/mlflow","descriptions":[{"lang":"en","value":"A command injection vulnerability exists in mlflow/mlflow when serving a model with `enable_mlserver=True`.
