An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-20837 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2018-20837/ (Markdown: https://insights.sbomify.com/CVE-2018-20837/index.md)","id":"CVE-2018-20837","markdown":"https://insights.sbomify.com/CVE-2018-20837/index.md","name":"CVE-2018-20837","record":{"aliases":["GHSA-36q9-65j8-xvpg"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Typesetter CMS","requires_auth":"high_privilege","summary":"Cross-site scripting vulnerability in Typesetter CMS allows attackers to inject malicious scripts via the admin menu, potentially leading to session hijacking or code execution.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"typesetter","vendor":"typesettercms"}],"cvss":{"score":4.8,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"include/admin/Menu/Ajax.php in Typesetter 5.1 has index.php/Admin/Menu/Ajax?cmd=AddHidden title XSS.","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 n/a","id":"CVE-2018-20837","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2018-20838"},"packages":[],"prev":{"headline":"Use after free in n/a","id":"CVE-2018-20836"},"products":["n/a"],"published":"2019-05-09","related":[{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2022-25523","kev_date_added":null,"published":"2022-03-25"},{"cvss_score":8.8,"headline":"Open redirect in n/a","id":"CVE-2018-6889","kev_date_added":null,"published":"2018-02-12"},{"cvss_score":8,"headline":"Cross-site request forgery in n/a","id":"CVE-2018-6888","kev_date_added":null,"published":"2018-02-12"},{"cvss_score":7.2,"headline":"File upload in n/a","id":"CVE-2020-25790","kev_date_added":null,"published":"2020-09-19"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2020-19511","kev_date_added":null,"published":"2021-06-21"},{"cvss_score":5.4,"headline":"Cross-site scripting in n/a","id":"CVE-2018-16639","kev_date_added":null,"published":"2019-05-13"},{"cvss_score":4.8,"headline":"Typesetter CMS Reflected XSS via Editing.php","id":"CVE-2025-71164","kev_date_added":null,"published":"2026-01-14"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"Cross-site scripting vulnerability in Typesetter CMS allows attackers to inject malicious scripts via the admin menu, potentially leading to session hijacking or code execution.","url":"https://insights.sbomify.com/CVE-2018-20837/"}
