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-2021-47621 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- io.github.classgraph:classgraph (Maven): affected all versions; fixed in 4.8.112\n- io.github.classgraph:classgraph (Maven): affected all versions; fixed in 4.8.112\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-2021-47621/ (Markdown: https://insights.sbomify.com/CVE-2021-47621/index.md)","id":"CVE-2021-47621","markdown":"https://insights.sbomify.com/CVE-2021-47621/index.md","name":"CVE-2021-47621","record":{"aliases":["ECHO-d016-3169-4d32","GHSA-v2xm-76pq-phcf","RHLW-2026-27d595c7dc400686","RHLW-2026-9bd677f780e42d38","ROOT-APP-MAVEN-CVE-2021-47621"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java classpath scanner","requires_auth":"none","summary":"ClassGraph library is vulnerable to XML External Entity attacks, allowing attackers to read files or cause denial of service.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"ClassGraph before 4.8.112 was not resistant to XML eXternal Entity (XXE) attacks.","ecosystems":["Maven"],"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":"ClassGraph XML External Entity Reference","id":"CVE-2021-47621","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"xxe","year":"2021"},"n_packages":2,"n_references":4,"next":{"headline":"scsi: ufs: Fix a deadlock in the error handler","id":"CVE-2021-47622"},"packages":[{"ecosystem":"Maven","fixed":["4.8.112"],"introduced":["0"],"last_affected":[],"package":"io.github.classgraph:classgraph","purl":null,"source":"GHSA-v2xm-76pq-phcf"},{"ecosystem":"Maven","fixed":["4.8.112"],"introduced":["0"],"last_affected":[],"package":"io.github.classgraph:classgraph","purl":"pkg:maven/io.github.classgraph/classgraph","source":"GHSA-v2xm-76pq-phcf"}],"prev":{"headline":"Bluetooth: refactor malicious adv data check","id":"CVE-2021-47620"},"products":["n/a"],"published":"2024-06-21","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-03-13","vendors":["n/a"]},"summary":"ClassGraph library is vulnerable to XML External Entity attacks, allowing attackers to read files or cause denial of service.","url":"https://insights.sbomify.com/CVE-2021-47621/"}
