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-2021-32796 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- @xmldom/xmldom (npm): affected all versions; fixed in 0.7.0\n- @xmldom/xmldom (npm): affected all versions; fixed in 0.7.0\n- xmldom (npm): affected all versions up to 0.6.0; no fix listed\n- xmldom (npm): affected all versions up to 0.6.0; 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-2021-32796/ (Markdown: https://insights.sbomify.com/CVE-2021-32796/index.md)","id":"CVE-2021-32796","markdown":"https://insights.sbomify.com/CVE-2021-32796/index.md","name":"CVE-2021-32796","record":{"aliases":["DEBIAN-CVE-2021-32796","GHSA-5fg8-2547-mr8q","UBUNTU-CVE-2021-32796"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["other"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript XML library","requires_auth":"none","summary":"Attackers can cause unexpected syntactic changes in XML processing by exploiting improper escaping of special characters in xmldom.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"xmldom","vendor":"xmldom_project"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-91","name":"XML Injection"},{"id":"CWE-116","name":"Improper Encoding or Escaping of Output"}],"description":"xmldom is an open source pure JavaScript W3C standard-based (XML DOM Level 2 Core) DOMParser and XMLSerializer module. xmldom versions 0.6.0 and older do not correctly escape special characters when serializing elements removed from their ancestor.
