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-2020-12827 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mjml (npm): affected all versions; fixed in 4.6.3\n- mjml (npm): affected all versions; fixed in 4.6.3\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-2020-12827/ (Markdown: https://insights.sbomify.com/CVE-2020-12827/index.md)","id":"CVE-2020-12827","markdown":"https://insights.sbomify.com/CVE-2020-12827/index.md","name":"CVE-2020-12827","record":{"aliases":["GHSA-4hch-r9xf-6vfr"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"MJML email library","requires_auth":"none","summary":"An attacker can read arbitrary files via path traversal in the mj-include directive of the MJML email library.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mjml","vendor":"mjml"}],"cvss":{"score":7.2,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"MJML prior to 4.6.3 contains a path traversal vulnerability when processing the mj-include directive within an MJML document.","ecosystems":["npm"],"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":"MJML vulnerable to path traversal","id":"CVE-2020-12827","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"path_traversal","year":"2020"},"n_packages":2,"n_references":7,"next":{"headline":"Command injection in n/a","id":"CVE-2020-12828"},"packages":[{"ecosystem":"npm","fixed":["4.6.3"],"introduced":["0"],"last_affected":[],"package":"mjml","purl":null,"source":"GHSA-4hch-r9xf-6vfr"},{"ecosystem":"npm","fixed":["4.6.3"],"introduced":["0"],"last_affected":[],"package":"mjml","purl":"pkg:npm/mjml","source":"GHSA-4hch-r9xf-6vfr"}],"prev":{"headline":"Integer overflow in n/a","id":"CVE-2020-12826"},"products":["n/a"],"published":"2020-06-17","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":"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":"2024-08-04","vendors":["n/a"]},"summary":"An attacker can read arbitrary files via path traversal in the mj-include directive of the MJML email library.","url":"https://insights.sbomify.com/CVE-2020-12827/"}
