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-2021-25951 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- xml2dict (PyPI): affected all versions; no fix listed\n- xml2dict (PyPI): affected all versions up to 0.2.2; no fix listed\n- XML2Dict (PyPI): affected all versions up to 0.2.2; 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-2021-25951/ (Markdown: https://insights.sbomify.com/CVE-2021-25951/index.md)","id":"CVE-2021-25951","markdown":"https://insights.sbomify.com/CVE-2021-25951/index.md","name":"CVE-2021-25951","record":{"aliases":["GHSA-gp6m-vqhm-5cm5","PYSEC-2021-349"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Python XML library","requires_auth":"none","summary":"An attacker can cause a denial of service in the XML2Dict library via an XML External Entity vulnerability.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mend","cpe":[{"product":"xml2dict","vendor":"xml2dict_project"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"XXE vulnerability in 'XML2Dict' version 0.2.2 allows an attacker to cause a denial of service.","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":"XML2Dict XML Entity Expansion Vulnerability","id":"CVE-2021-25951","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"xxe","year":"2021"},"n_packages":3,"n_references":1,"next":{"headline":"Prototype polluation in just-safe-set","id":"CVE-2021-25952"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.2.2"],"package":"XML2Dict","purl":null,"source":"GHSA-gp6m-vqhm-5cm5"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":[],"package":"xml2dict","purl":"pkg:pypi/xml2dict","source":"PYSEC-2021-349"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.2.2"],"package":"xml2dict","purl":"pkg:pypi/xml2dict","source":"GHSA-gp6m-vqhm-5cm5"}],"prev":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2021-25950"},"products":["XML2Dict"],"published":"2021-06-30","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":"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":"2024-08-03","vendors":["n/a"]},"summary":"An attacker can cause a denial of service in the XML2Dict library via an XML External Entity vulnerability.","url":"https://insights.sbomify.com/CVE-2021-25951/"}
