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-2021-4103 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- vditor (npm): affected all versions; fixed in 3.8.11\n- vditor (npm): affected all versions; fixed in 3.8.11\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-2021-4103/ (Markdown: https://insights.sbomify.com/CVE-2021-4103/index.md)","id":"CVE-2021-4103","markdown":"https://insights.sbomify.com/CVE-2021-4103/index.md","name":"CVE-2021-4103","record":{"aliases":["GHSA-cxm3-v4mv-6mh8"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript Markdown Editor","requires_auth":"low_privilege","summary":"Stored Cross-Site Scripting in the vditor library allows attackers to inject malicious scripts into web pages viewed by other users.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntrdev","cpe":[{"product":"vditor","vendor":"b3log"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:H/A:L","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Cross-site Scripting (XSS) - Stored in GitHub repository vanessa219/vditor prior to 1.0.34.","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 (XSS) - Stored in vanessa219/vditor","id":"CVE-2021-4103","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"xss","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Deserialization of untrusted data in JMSAppender in Apache Log4j 1.2","id":"CVE-2021-4104"},"packages":[{"ecosystem":"npm","fixed":["3.8.11"],"introduced":["0"],"last_affected":[],"package":"vditor","purl":null,"source":"GHSA-cxm3-v4mv-6mh8"},{"ecosystem":"npm","fixed":["3.8.11"],"introduced":["0"],"last_affected":[],"package":"vditor","purl":"pkg:npm/vditor","source":"GHSA-cxm3-v4mv-6mh8"}],"prev":{"headline":"Google Chromium V8 Use-After-Free","id":"CVE-2021-4102"},"products":["vanessa219/vditor"],"published":"2022-01-23","related":[{"cvss_score":6.6,"headline":"Cross-site Scripting (XSS) - Stored in vanessa219/vditor","id":"CVE-2022-0341","kev_date_added":null,"published":"2022-03-14"},{"cvss_score":6.1,"headline":"Vditor allows Cross-site Scripting via an attribute of an `A` element","id":"CVE-2024-34449","kev_date_added":null,"published":"2024-05-03"},{"cvss_score":6.1,"headline":"vditor vulnerable to Cross-site Scripting","id":"CVE-2021-32855","kev_date_added":null,"published":"2023-02-20"},{"cvss_score":6.1,"headline":"Cross-site Scripting (XSS) - Stored in vanessa219/vditor","id":"CVE-2022-0350","kev_date_added":null,"published":"2022-03-31"},{"cvss_score":5.9,"headline":"Path traversal in n/a","id":"CVE-2024-39150","kev_date_added":null,"published":"2024-07-05"}],"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":"2024-08-03","vendors":["vanessa219"]},"summary":"Stored Cross-Site Scripting in the vditor library allows attackers to inject malicious scripts into web pages viewed by other users.","url":"https://insights.sbomify.com/CVE-2021-4103/"}
