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-2021-35514 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- narou (RubyGems): affected all versions; fixed in 3.8.0\n- narou (RubyGems): affected all versions; fixed in 3.8.0\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-2021-35514/ (Markdown: https://insights.sbomify.com/CVE-2021-35514/index.md)","id":"CVE-2021-35514","markdown":"https://insights.sbomify.com/CVE-2021-35514/index.md","name":"CVE-2021-35514","record":{"aliases":["GHSA-gwrj-88fp-5m36"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Ruby Narou library","requires_auth":"none","summary":"Attackers can execute arbitrary Ruby code by injecting malicious payloads into novel title or author fields in the Narou library.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"narou","vendor":"narou_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-94","name":"Improper Control of Generation of Code"}],"description":"Narou (aka Narou.rb) before 3.8.0 allows Ruby Code Injection via the title name or author name of a novel.","ecosystems":["RubyGems"],"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":"Code injection in Narou","id":"CVE-2021-35514","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"RubyGems","product":null,"products":[],"type":"code_injection","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Apache Commons Compress 1.6 to 1.20 denial of service vulnerability","id":"CVE-2021-35515"},"packages":[{"ecosystem":"RubyGems","fixed":["3.8.0"],"introduced":["0"],"last_affected":[],"package":"narou","purl":null,"source":"GHSA-gwrj-88fp-5m36"},{"ecosystem":"RubyGems","fixed":["3.8.0"],"introduced":["0"],"last_affected":[],"package":"narou","purl":"pkg:gem/narou","source":"GHSA-gwrj-88fp-5m36"}],"prev":{"headline":"Cross-site Scripting in Mermaid","id":"CVE-2021-35513"},"products":["n/a"],"published":"2021-06-28","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":"Attackers can execute arbitrary Ruby code by injecting malicious payloads into novel title or author fields in the Narou library.","url":"https://insights.sbomify.com/CVE-2021-35514/"}
