Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-28847 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- valine (npm): affected all versions; fixed in 1.4.15\n- valine (npm): affected all versions; fixed in 1.4.15\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-2020-28847/ (Markdown: https://insights.sbomify.com/CVE-2020-28847/index.md)","id":"CVE-2020-28847","markdown":"https://insights.sbomify.com/CVE-2020-28847/index.md","name":"CVE-2020-28847","record":{"aliases":["GHSA-6xvq-2gj8-4276"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Valine comment library","requires_auth":"low_privilege","summary":"Cross-site scripting in Valine allows attackers to inject malicious scripts via the nick parameter, potentially compromising user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"valine","vendor":"valine.js"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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":"Cross Site Scripting (XSS) vulnerability in xCss Valine v1.4.14 via the nick parameter to /classes/Comment.","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":"Cross site scripting in valine","id":"CVE-2020-28847","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"xss","year":"2020"},"n_packages":2,"n_references":1,"next":{"headline":"Code injection in n/a","id":"CVE-2020-28848"},"packages":[{"ecosystem":"npm","fixed":["1.4.15"],"introduced":["0"],"last_affected":[],"package":"valine","purl":null,"source":"GHSA-6xvq-2gj8-4276"},{"ecosystem":"npm","fixed":["1.4.15"],"introduced":["0"],"last_affected":[],"package":"valine","purl":"pkg:npm/valine","source":"GHSA-6xvq-2gj8-4276"}],"prev":{"headline":"Cross-site request forgery in n/a","id":"CVE-2020-28846"},"products":["n/a"],"published":"2022-04-05","related":[{"cvss_score":9.6,"headline":"Valine code injection vulnerability","id":"CVE-2022-38545","kev_date_added":null,"published":"2022-09-19"},{"cvss_score":6.1,"headline":"Valine HTML Injection","id":"CVE-2018-19289","kev_date_added":null,"published":"2018-11-15"},{"cvss_score":5.3,"headline":"Denial of service in Valine","id":"CVE-2021-34801","kev_date_added":null,"published":"2021-06-16"}],"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":"Cross-site scripting in Valine allows attackers to inject malicious scripts via the nick parameter, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2020-28847/"}
