An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-0545 exists.\n\nAffected packages and fixed versions:\n- mlflow (PyPI): affected all versions up to 3.10.1; no fix listed\n- mlflow (PyPI): affected all versions up to 3.10.1; no fix listed\n- mlflow (PyPI): affected all versions up to 3.10.1; no fix listed\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-0545/ (Markdown: https://insights.sbomify.com/CVE-2026-0545/index.md)","id":"CVE-2026-0545","markdown":"https://insights.sbomify.com/CVE-2026-0545/index.md","name":"CVE-2026-0545","record":{"aliases":["GHSA-7qhf-v65m-g5f3","MINI-54gx-rj97-rrc8","PYSEC-2026-419"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"MLflow server","requires_auth":"none","summary":"Unauthenticated attackers can execute jobs in MLflow when basic-auth is enabled, potentially leading to remote code execution or denial of service.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntr_ai","cpe":[{"product":"mlflow","vendor":"lfprojects"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"In mlflow/mlflow, the FastAPI job endpoints under `/ajax-api/3.0/jobs/*` are not protected by authentication or authorization when the `basic-auth` app is enabled. This vulnerability affects the latest version of the repository. If job execution is enabled (`MLFLOW_SERVER_ENABLE_JOB_EXECUTION=true`) and any job function is allowlisted, any network client can submit, read, search, and cancel jobs without credentials, bypassing basic-auth entirely. This can lead to unauthenticated remote code execution if allowed jobs perform privileged actions such as shell execution or filesystem changes. Even if jobs are deemed safe, this still constitutes an authentication bypass, potentially resulting in job spam, denial of service (DoS), or data exposure in job results.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2026/CVE-2026-0545.yaml","stars":null,"title":"MLflow Job API - Authentication Bypass"}],"tier":"weaponised"},"has_fix":false,"headline":"Missing Authentication for Critical Function in mlflow/mlflow","id":"CVE-2026-0545","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":"lfprojects:mlflow","products":["lfprojects:mlflow"],"type":"missing_authorization","year":"2026"},"n_packages":3,"n_references":1,"next":{"headline":"code-projects Content Management System search.php sql injection","id":"CVE-2026-0546"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["3.10.1"],"package":"mlflow","purl":null,"source":"GHSA-7qhf-v65m-g5f3"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["3.10.1"],"package":"mlflow","purl":"pkg:pypi/mlflow","source":"GHSA-7qhf-v65m-g5f3"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["3.10.1"],"package":"mlflow","purl":"pkg:pypi/mlflow","source":"PYSEC-2026-419"}],"prev":{"headline":"itsourcecode School Management System index.php sql injection","id":"CVE-2026-0544"},"products":["mlflow/mlflow"],"published":"2026-04-03","related":[{"cvss_score":9.3,"headline":"MLflow Server-Side Request Forgery","id":"CVE-2026-64849","kev_date_added":"2026-08-19","published":"2026-08-17"},{"cvss_score":10,"headline":"Command Injection in mlflow/mlflow","id":"CVE-2025-15379","kev_date_added":null,"published":"2026-03-30"},{"cvss_score":10,"headline":"Remote Code Execution due to Full Controlled File Write in mlflow/mlflow","id":"CVE-2024-0520","kev_date_added":null,"published":"2024-06-06"},{"cvss_score":10,"headline":"Path Traversal: '\\..\\filename'","id":"CVE-2023-6977","kev_date_added":null,"published":"2023-12-20"},{"cvss_score":10,"headline":"Improper Neutralization of Special Elements Used in a Template Engine in mlflow/mlflow","id":"CVE-2023-6709","kev_date_added":null,"published":"2023-12-12"},{"cvss_score":10,"headline":"MLflow Arbitrary File Upload","id":"CVE-2023-6015","kev_date_added":null,"published":"2023-11-16"},{"cvss_score":10,"headline":"MLflow Arbitrary File Write","id":"CVE-2023-6018","kev_date_added":null,"published":"2023-11-16"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-28","vendors":["mlflow"]},"summary":"Unauthenticated attackers can execute jobs in MLflow when basic-auth is enabled, potentially leading to remote code execution or denial of service.","url":"https://insights.sbomify.com/CVE-2026-0545/"}
