An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-31223 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- snorkel (PyPI): affected all versions up to 0.10.0; no fix listed\n- snorkel (PyPI): affected all versions up to 0.10.0; no fix listed\n- snorkel (PyPI): affected all versions up to 0.10.0; 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-2026-31223/ (Markdown: https://insights.sbomify.com/CVE-2026-31223/index.md)","id":"CVE-2026-31223","markdown":"https://insights.sbomify.com/CVE-2026-31223/index.md","name":"CVE-2026-31223","record":{"aliases":["GHSA-fq92-qc8f-482v","PYSEC-2026-3069"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Python snorkel library","requires_auth":"none","summary":"A remote attacker can execute arbitrary code by providing a malicious pickle file to the BaseLabeler.load method in the snorkel library.","user_interaction":"required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"snorkel","vendor":"snorkel"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"The snorkel library thru v0.10.0 contains a critical insecure deserialization vulnerability (CWE-502) in the BaseLabeler.load() method of the BaseLabeler class. The method loads serialized labeler models using the unsafe pickle.load() function on user-supplied file paths without any validation or security controls. Python's pickle module is inherently dangerous for deserializing untrusted data, as it can execute arbitrary code during the deserialization process. A remote attacker can exploit this by providing a maliciously crafted pickle file, leading to arbitrary code execution on the victim's system when the file is loaded via the vulnerable method.","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":false,"headline":"Snorkel BaseLabeler.load uses an unsafe pickle.load","id":"CVE-2026-31223","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":3,"n_references":2,"next":{"headline":"Snorkel MultitaskClassifier.load uses an unsafe torch.load","id":"CVE-2026-31224"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.10.0"],"package":"snorkel","purl":null,"source":"GHSA-fq92-qc8f-482v"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.10.0"],"package":"snorkel","purl":"pkg:pypi/snorkel","source":"GHSA-fq92-qc8f-482v"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.10.0"],"package":"snorkel","purl":"pkg:pypi/snorkel","source":"PYSEC-2026-3069"}],"prev":{"headline":"Snorkel Trainer.load uses an unsafe torch.load","id":"CVE-2026-31222"},"products":["n/a"],"published":"2026-05-12","related":[{"cvss_score":8.8,"headline":"Snorkel Trainer.load uses an unsafe torch.load","id":"CVE-2026-31222","kev_date_added":null,"published":"2026-05-12"},{"cvss_score":8.8,"headline":"Snorkel MultitaskClassifier.load uses an unsafe torch.load","id":"CVE-2026-31224","kev_date_added":null,"published":"2026-05-12"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-15","vendors":["n/a"]},"summary":"A remote attacker can execute arbitrary code by providing a malicious pickle file to the BaseLabeler.load method in the snorkel library.","url":"https://insights.sbomify.com/CVE-2026-31223/"}
