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-2022-21158 in the wild and no public exploit code.\n\nAffected product: MarkText. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2022-21158/ (Markdown: https://insights.sbomify.com/CVE-2022-21158/index.md)","id":"CVE-2022-21158","markdown":"https://insights.sbomify.com/CVE-2022-21158/index.md","name":"CVE-2022-21158","record":{"aliases":["GHSA-xfpv-q4q6-7j43"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Markdown editor","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary scripts on user machines via malicious links in MarkText documents, requiring an upgrade to secure the application.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"marktext","vendor":"marktext"}],"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":"A stored cross-site scripting vulnerability in marktext versions prior to v0.17.0 due to improper handling of the link (with javascript: scheme) inside the document may allow an attacker to execute an arbitrary script on the PC of the user using marktext.","ecosystems":[],"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 MarkText","id":"CVE-2022-21158","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2022"},"n_packages":0,"n_references":2,"next":{"headline":"Denial of service in libiec61850","id":"CVE-2022-21159"},"packages":[],"prev":{"headline":"Information disclosure in Intel(R) Smart Campus Android application","id":"CVE-2022-21157"},"products":["MarkText"],"published":"2022-03-07","related":[{"cvss_score":9.6,"headline":"Cross-site scripting in n/a","id":"CVE-2022-25069","kev_date_added":null,"published":"2022-03-05"},{"cvss_score":9.6,"headline":"Cross-site scripting in n/a","id":"CVE-2021-29996","kev_date_added":null,"published":"2021-04-05"},{"cvss_score":9,"headline":"Cross-site scripting in n/a","id":"CVE-2022-24123","kev_date_added":null,"published":"2022-01-29"},{"cvss_score":8.6,"headline":"MarkText DOM-Based Cross-site Scripting leading to Remote Code Execution","id":"CVE-2023-2318","kev_date_added":null,"published":"2023-08-19"},{"cvss_score":8.3,"headline":"Cross-site scripting in n/a","id":"CVE-2020-27176","kev_date_added":null,"published":"2020-10-16"},{"cvss_score":5.3,"headline":"MarkText WSH JScript code injection","id":"CVE-2023-1004","kev_date_added":null,"published":"2023-02-24"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":["MarkText"]},"summary":"Attackers can execute arbitrary scripts on user machines via malicious links in MarkText documents, requiring an upgrade to secure the application.","url":"https://insights.sbomify.com/CVE-2022-21158/"}
