Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-6730 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- transformers (PyPI): affected all versions; fixed in 4.36.0\n- transformers (PyPI): affected all versions; fixed in 4.36.0\n- transformers (PyPI): affected all versions; fixed in 4.36.0\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-2023-6730/ (Markdown: https://insights.sbomify.com/CVE-2023-6730/index.md)","id":"CVE-2023-6730","markdown":"https://insights.sbomify.com/CVE-2023-6730/index.md","name":"CVE-2023-6730","record":{"aliases":["GHSA-3863-2447-669p","PYSEC-2023-300"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Python ML library","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary code by exploiting unsafe deserialization in the Hugging Face Transformers library.","user_interaction":"required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntr_ai","cpe":[{"product":"transformers","vendor":"huggingface"}],"cvss":{"score":9,"severity":"critical","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Deserialization of Untrusted Data in GitHub repository huggingface/transformers prior to 4.36.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Deserialization of Untrusted Data in huggingface/transformers","id":"CVE-2023-6730","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"deserialization","year":"2023"},"n_packages":3,"n_references":2,"next":{"headline":"WP Show Posts \u003c= 1.1.5 - Improper Authorization to Information Exposure","id":"CVE-2023-6731"},"packages":[{"ecosystem":"PyPI","fixed":["4.36.0"],"introduced":["0"],"last_affected":[],"package":"transformers","purl":null,"source":"GHSA-3863-2447-669p"},{"ecosystem":"PyPI","fixed":["4.36.0"],"introduced":["0"],"last_affected":[],"package":"transformers","purl":"pkg:pypi/transformers","source":"GHSA-3863-2447-669p"},{"ecosystem":"PyPI","fixed":["4.36.0"],"introduced":["0"],"last_affected":[],"package":"transformers","purl":"pkg:pypi/transformers","source":"PYSEC-2023-300"}],"prev":{"headline":"Nokia SR OS: File Access Security Vulnerability","id":"CVE-2023-6729"},"products":["huggingface/transformers"],"published":"2023-12-19","related":[{"cvss_score":9.6,"headline":"Deserialization of Untrusted Data in huggingface/transformers","id":"CVE-2023-7018","kev_date_added":null,"published":"2023-12-20"},{"cvss_score":8.8,"headline":"Hugging Face Transformers MaskFormer Model Deserialization of Untrusted Data Remote Code Execution Vulnerability","id":"CVE-2024-11393","kev_date_added":null,"published":"2024-11-22"},{"cvss_score":8.8,"headline":"Hugging Face Transformers Trax Model Deserialization of Untrusted Data Remote Code Execution Vulnerability","id":"CVE-2024-11394","kev_date_added":null,"published":"2024-11-22"},{"cvss_score":8,"headline":"Policy Bypass in LightGlue Nested Config Resolution in huggingface/transformers","id":"CVE-2026-5241","kev_date_added":null,"published":"2026-06-03"},{"cvss_score":7.8,"headline":"Arbitrary Remote Code Execution via `_attn_implementation_internal` Config Injection in huggingface/transformers","id":"CVE-2026-4372","kev_date_added":null,"published":"2026-05-24"},{"cvss_score":7.8,"headline":"Hugging Face Transformers Perceiver Model Deserialization of Untrusted Data Remote Code Execution Vulnerability","id":"CVE-2025-14920","kev_date_added":null,"published":"2025-12-23"}],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-02","vendors":["huggingface"]},"summary":"Attackers can execute arbitrary code by exploiting unsafe deserialization in the Hugging Face Transformers library.","url":"https://insights.sbomify.com/CVE-2023-6730/"}
