An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-44900 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- py7zr (PyPI): affected all versions; fixed in 0.20.1\n- py7zr (PyPI): affected all versions; fixed in 0.20.1\n- py7zr (PyPI): affected all versions; fixed in 0.20.1\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-2022-44900/ (Markdown: https://insights.sbomify.com/CVE-2022-44900/index.md)","id":"CVE-2022-44900","markdown":"https://insights.sbomify.com/CVE-2022-44900/index.md","name":"CVE-2022-44900","record":{"aliases":["DEBIAN-CVE-2022-44900","DSA-5652-1","GHSA-m8xw-9x5x-6vh3","PYSEC-2022-42998","UBUNTU-CVE-2022-44900","USN-7030-1","openSUSE-SU-2024:12586-1","openSUSE-SU-2025:15101-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Python py7zr library","requires_auth":"none","summary":"Attackers can write arbitrary files to the filesystem by extracting a crafted 7z archive using the py7zr library.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"py7zr","vendor":"py7zr_project"}],"cvss":{"score":9.1,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"A directory traversal vulnerability in the SevenZipFile.extractall() function of the python library py7zr v0.20.0 and earlier allows attackers to write arbitrary files via extracting a crafted 7z file.","ecosystems":["PyPI","openSUSE:Tumbleweed"],"exploits":{"exploitdb":0,"first_seen":"2023-01-21","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2023-01-21T14:52:59Z","kind":"github_poc","ref":"https://github.com/0xless/CVE-2022-44900-demo-lab","stars":1,"title":"Demo webapp vulnerable to CVE-2022-44900"}],"tier":"poc_unverified"},"has_fix":true,"headline":"py7zr directory traversal vulnerability","id":"CVE-2022-44900","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"path_traversal","year":"2022"},"n_packages":4,"n_references":3,"next":{"headline":"Memory corruption in n/a","id":"CVE-2022-44910"},"packages":[{"ecosystem":"PyPI","fixed":["0.20.1"],"introduced":["0"],"last_affected":[],"package":"py7zr","purl":null,"source":"GHSA-m8xw-9x5x-6vh3"},{"ecosystem":"PyPI","fixed":["0.20.1"],"introduced":["0"],"last_affected":[],"package":"py7zr","purl":"pkg:pypi/py7zr","source":"GHSA-m8xw-9x5x-6vh3"},{"ecosystem":"PyPI","fixed":["0.20.1"],"introduced":["0"],"last_affected":[],"package":"py7zr","purl":"pkg:pypi/py7zr","source":"PYSEC-2022-42998"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["0.20.8-2.6"],"introduced":["0"],"last_affected":[],"package":"python-py7zr","purl":"pkg:rpm/opensuse/python-py7zr\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2025:15101-1"}],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2022-44898"},"products":["n/a"],"published":"2022-12-06","related":[],"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":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-04-23","vendors":["n/a"]},"summary":"Attackers can write arbitrary files to the filesystem by extracting a crafted 7z archive using the py7zr library.","url":"https://insights.sbomify.com/CVE-2022-44900/"}
