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-2020-8823 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- sockjs (npm): affected all versions; fixed in 0.3.0\n- sockjs (npm): affected all versions; fixed in 0.3.0\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-2020-8823/ (Markdown: https://insights.sbomify.com/CVE-2020-8823/index.md)","id":"CVE-2020-8823","markdown":"https://insights.sbomify.com/CVE-2020-8823/index.md","name":"CVE-2020-8823","record":{"aliases":["GHSA-hh8v-jmh3-9437","SNYK-JS-SOCKJS-548397"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SockJS JavaScript library","requires_auth":"none","summary":"Reflected XSS in SockJS allows attackers to execute arbitrary scripts in victim browsers via the callback parameter.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"sockjs","vendor":"sockjs_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-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"htmlfile in lib/transport/htmlfile.js in SockJS before 0.3.0 is vulnerable to Reflected XSS via the /htmlfile c (aka callback) parameter.","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 SocksJS-node","id":"CVE-2020-8823","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"xss","year":"2020"},"n_packages":2,"n_references":4,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-8824"},"packages":[{"ecosystem":"npm","fixed":["0.3.0"],"introduced":["0"],"last_affected":[],"package":"sockjs","purl":null,"source":"GHSA-hh8v-jmh3-9437"},{"ecosystem":"npm","fixed":["0.3.0"],"introduced":["0"],"last_affected":[],"package":"sockjs","purl":"pkg:npm/sockjs","source":"GHSA-hh8v-jmh3-9437"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-8822"},"products":["n/a"],"published":"2020-02-10","related":[{"cvss_score":5.3,"headline":"Denial of Service (DoS)","id":"CVE-2020-7693","kev_date_added":null,"published":"2020-07-09"}],"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":"Reflected XSS in SockJS allows attackers to execute arbitrary scripts in victim browsers via the callback parameter.","url":"https://insights.sbomify.com/CVE-2020-8823/"}
