{"id":"CVE-2025-10279","summary":"Privilege Escalation in mlflow/mlflow","details":"In mlflow version 2.20.3, the temporary directory used for creating Python virtual environments is assigned insecure world-writable permissions (0o777). This vulnerability allows an attacker with write access to the `/tmp` directory to exploit a race condition and overwrite `.py` files in the virtual environment, leading to arbitrary code execution. The issue is resolved in version 3.4.0.","aliases":["BIT-mlflow-2025-10279","GHSA-4x5p-f36r-mxxr","PYSEC-2026-1639"],"modified":"2026-08-12T03:51:27.494871423Z","published":"2026-02-02T10:36:22.810Z","database_specific":{"cna_assigner":"@huntr_ai","cwe_ids":["CWE-379"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/10xxx/CVE-2025-10279.json"},"references":[{"type":"WEB","url":"https://huntr.com/bounties/01d3b81e-13d1-43aa-b91a-443aec68bdc8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/10xxx/CVE-2025-10279.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-10279"},{"type":"FIX","url":"https://github.com/mlflow/mlflow/commit/1d7c8d4cf0a67d407499a8a4ffac387ea4f8194a"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mlflow/mlflow","events":[{"introduced":"0"},{"fixed":"78d075062b120597050bf2b3839a426feea5ea4c"},{"fixed":"1d7c8d4cf0a67d407499a8a4ffac387ea4f8194a"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:lfprojects:mlflow:*:-:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"3.4.0"}]}}],"versions":["v3.4.0rc0","nightly","v3.0.0","v2.2.0","v1.7.0","1.0.0","v0.8.1","v0.8.0","v0.7","v0.6.0","v0.5.0","v0.4.2","v0.4.1","v0.4.0","v0.3.0","v0.2.1","v0.2.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-10279.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
