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-2020-14001 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- kramdown (RubyGems): affected all versions; fixed in 2.3.0\n- kramdown (RubyGems): affected all versions; fixed in 2.3.0\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-2020-14001/ (Markdown: https://insights.sbomify.com/CVE-2020-14001/index.md)","id":"CVE-2020-14001","markdown":"https://insights.sbomify.com/CVE-2020-14001/index.md","name":"CVE-2020-14001","record":{"aliases":["DEBIAN-CVE-2020-14001","DLA-2316-1","DSA-4743-1","GHSA-mqm2-cgpr-p4m6","OESA-2021-1280","SUSE-SU-2022:3259-1","UBUNTU-CVE-2020-14001","USN-4562-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Ruby kramdown gem","requires_auth":"none","summary":"The kramdown gem allows remote attackers to execute arbitrary Ruby code or read sensitive files via the template option.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"kramdown","vendor":"kramdown_project"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"The kramdown gem before 2.3.0 for Ruby processes the template option inside Kramdown documents by default, which allows unintended read access (such as template=\"/etc/passwd\") or unintended embedded Ruby code execution (such as a string that begins with template=\"string://\u003c%= `).
