It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-46364 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- info.magnolia:magnolia-core (Maven): affected all versions; fixed in 6.2.4\n- info.magnolia:magnolia-core (Maven): affected all versions; fixed in 6.2.4\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-2021-46364/ (Markdown: https://insights.sbomify.com/CVE-2021-46364/index.md)","id":"CVE-2021-46364","markdown":"https://insights.sbomify.com/CVE-2021-46364/index.md","name":"CVE-2021-46364","record":{"aliases":["GHSA-pwr6-p3fh-grc2"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Magnolia CMS","requires_auth":"none","summary":"Attackers can execute arbitrary code in Magnolia CMS by submitting a crafted YAML file due to unsafe deserialization in the Snake YAML parser.","user_interaction":"required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"magnolia_cms","vendor":"magnolia-cms"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/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":"A vulnerability in the Snake YAML parser of Magnolia CMS v6.2.3 and below allows attackers to execute arbitrary code via a crafted YAML file.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":"2023-11-23","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2023-11-23T22:37:01Z","kind":"github_poc","ref":"https://github.com/mbadanoiu/CVE-2021-46364","stars":1,"title":"CVE-2021-46364: YAML Deserialization in Magnolia CMS"}],"tier":"poc_unverified"},"has_fix":true,"headline":"Deserialization of Untrusted Data in Magnolia CMS","id":"CVE-2021-46364","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"deserialization","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Improper Restriction of XML External Entity Reference in Magnolia CMS","id":"CVE-2021-46365"},"packages":[{"ecosystem":"Maven","fixed":["6.2.4"],"introduced":["0"],"last_affected":[],"package":"info.magnolia:magnolia-core","purl":null,"source":"GHSA-pwr6-p3fh-grc2"},{"ecosystem":"Maven","fixed":["6.2.4"],"introduced":["0"],"last_affected":[],"package":"info.magnolia:magnolia-core","purl":"pkg:maven/info.magnolia/magnolia-core","source":"GHSA-pwr6-p3fh-grc2"}],"prev":{"headline":"Arbitrary code execution in Magnolia CMS","id":"CVE-2021-46363"},"products":["n/a"],"published":"2022-02-11","related":[{"cvss_score":9.8,"headline":"Arbitrary code execution in Magnolia CMS","id":"CVE-2021-46361","kev_date_added":null,"published":"2022-02-11"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2021-46362","kev_date_added":null,"published":"2022-02-11"},{"cvss_score":8.8,"headline":"Cross-Site Request Forgery in Magnolia CMS","id":"CVE-2021-46366","kev_date_added":null,"published":"2022-02-11"},{"cvss_score":7.8,"headline":"Arbitrary code execution in Magnolia CMS","id":"CVE-2021-46363","kev_date_added":null,"published":"2022-02-11"},{"cvss_score":7.8,"headline":"Improper Restriction of XML External Entity Reference in Magnolia CMS","id":"CVE-2021-46365","kev_date_added":null,"published":"2022-02-11"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2022-33098","kev_date_added":null,"published":"2022-07-07"}],"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":"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can execute arbitrary code in Magnolia CMS by submitting a crafted YAML file due to unsafe deserialization in the Snake YAML parser.","url":"https://insights.sbomify.com/CVE-2021-46364/"}
