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-2020-27428 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- scratch-svg-renderer (npm): affected all versions up to 0.2.0; no fix listed\n- scratch-svg-renderer (npm): affected all versions up to 0.2.0; no fix listed\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-2020-27428/ (Markdown: https://insights.sbomify.com/CVE-2020-27428/index.md)","id":"CVE-2020-27428","markdown":"https://insights.sbomify.com/CVE-2020-27428/index.md","name":"CVE-2020-27428","record":{"aliases":["GHSA-h3vq-wv8j-36gw"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Scratch SVG renderer","requires_auth":"none","summary":"Attackers can execute arbitrary scripts via crafted sb3 files in the Scratch-Svg-Renderer library, potentially compromising user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"scratch-svg-renderer","vendor":"mit"}],"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-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A DOM-based cross-site scripting (XSS) vulnerability in Scratch-Svg-Renderer v0.2.0 allows attackers to execute arbitrary web scripts or HTML via a crafted sb3 file.","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":false,"headline":"Cross-site Scripting in Scratch-Svg-Renderer","id":"CVE-2020-27428","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"xss","year":"2020"},"n_packages":2,"n_references":1,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-27449"},"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["0.2.0"],"package":"scratch-svg-renderer","purl":null,"source":"GHSA-h3vq-wv8j-36gw"},{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":["0.2.0"],"package":"scratch-svg-renderer","purl":"pkg:npm/scratch-svg-renderer","source":"GHSA-h3vq-wv8j-36gw"}],"prev":{"headline":"Denial of service in n/a","id":"CVE-2020-27423"},"products":["n/a"],"published":"2022-01-05","related":[{"cvss_score":9.6,"headline":"Cross-site Scripting (XSS)","id":"CVE-2020-7750","kev_date_added":null,"published":"2020-10-21"}],"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 scripts via crafted sb3 files in the Scratch-Svg-Renderer library, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2020-27428/"}
