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-2020-23849 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- jsoneditor (npm): affected all versions; fixed in 9.0.2\n- jsoneditor (npm): affected all versions; fixed in 9.0.2\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-2020-23849/ (Markdown: https://insights.sbomify.com/CVE-2020-23849/index.md)","id":"CVE-2020-23849","markdown":"https://insights.sbomify.com/CVE-2020-23849/index.md","name":"CVE-2020-23849","record":{"aliases":["GHSA-q854-j362-cfq9"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"JSON editor library","requires_auth":"none","summary":"Attackers can execute arbitrary JavaScript in the tree mode of the jsoneditor library via stored XSS, potentially compromising user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"jsoneditor","vendor":"jsoneditoronline"}],"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":"Stored XSS was discovered in the tree mode of jsoneditor before 9.0.2 through injecting and executing JavaScript.","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 jsoneditor","id":"CVE-2020-23849","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"xss","year":"2020"},"n_packages":2,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2020-23851"},"packages":[{"ecosystem":"npm","fixed":["9.0.2"],"introduced":["0"],"last_affected":[],"package":"jsoneditor","purl":null,"source":"GHSA-q854-j362-cfq9"},{"ecosystem":"npm","fixed":["9.0.2"],"introduced":["0"],"last_affected":[],"package":"jsoneditor","purl":"pkg:npm/jsoneditor","source":"GHSA-q854-j362-cfq9"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-23839"},"products":["n/a"],"published":"2021-01-11","related":[{"cvss_score":5.3,"headline":"Inefficient Regular Expression Complexity in josdejong/jsoneditor","id":"CVE-2021-3822","kev_date_added":null,"published":"2021-09-27"}],"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 JavaScript in the tree mode of the jsoneditor library via stored XSS, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2020-23849/"}
