An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-16254 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- chartkick (RubyGems): affected all versions; fixed in 3.4.0\n- chartkick (RubyGems): affected all versions; fixed in 3.4.0\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-2020-16254/ (Markdown: https://insights.sbomify.com/CVE-2020-16254/index.md)","id":"CVE-2020-16254","markdown":"https://insights.sbomify.com/CVE-2020-16254/index.md","name":"CVE-2020-16254","record":{"aliases":["GHSA-3j95-fjv2-3m4p"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Ruby Chartkick gem","requires_auth":"none","summary":"An attacker can inject malicious CSS into Chartkick charts, potentially leading to cross-site scripting attacks in Ruby applications.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"chartkick","vendor":"chartkick_project"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"The Chartkick gem through 3.3.2 for Ruby allows Cascading Style Sheets (CSS) Injection (without attribute).","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":"CSS Injection in Chartkick gem","id":"CVE-2020-16254","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"RubyGems","product":null,"products":[],"type":"xss","year":"2020"},"n_packages":2,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-16255"},"packages":[{"ecosystem":"RubyGems","fixed":["3.4.0"],"introduced":["0"],"last_affected":[],"package":"chartkick","purl":null,"source":"GHSA-3j95-fjv2-3m4p"},{"ecosystem":"RubyGems","fixed":["3.4.0"],"introduced":["0"],"last_affected":[],"package":"chartkick","purl":"pkg:gem/chartkick","source":"GHSA-3j95-fjv2-3m4p"}],"prev":{"headline":"PgHero gem allows CSRF","id":"CVE-2020-16253"},"products":["n/a"],"published":"2020-08-05","related":[{"cvss_score":4.7,"headline":"Cross-site Scripting in Chartkick","id":"CVE-2019-12732","kev_date_added":null,"published":"2019-06-06"}],"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 inject malicious CSS into Chartkick charts, potentially leading to cross-site scripting attacks in Ruby applications.","url":"https://insights.sbomify.com/CVE-2020-16254/"}
