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-2026-40201 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- @diplodoc/search-extension (npm): affected from 1.0.0; fixed in 3.0.5\n- @diplodoc/search-extension (npm): affected from 1.0.0; fixed in 3.0.5\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-2026-40201/ (Markdown: https://insights.sbomify.com/CVE-2026-40201/index.md)","id":"CVE-2026-40201","markdown":"https://insights.sbomify.com/CVE-2026-40201/index.md","name":"CVE-2026-40201","record":{"aliases":["GHSA-rjmp-rwj4-mv82"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"npm search extension","requires_auth":"low_privilege","summary":"Stored XSS in @diplodoc/search-extension allows attackers to execute scripts via malicious Markdown titles, affecting users of the library.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cna","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":"@diplodoc/search-extension 1.0.0 through 3.x before 3.0.3 allows stored XSS via the title in a .md file.","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":"@diplodoc/search-extension allows stored XSS via Markdown file title","id":"CVE-2026-40201","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"xss","year":"2026"},"n_packages":2,"n_references":4,"next":{"headline":"Information disclosure in OX Dovecot CE","id":"CVE-2026-40203"},"packages":[{"ecosystem":"npm","fixed":["3.0.5"],"introduced":["1.0.0"],"last_affected":[],"package":"@diplodoc/search-extension","purl":null,"source":"GHSA-rjmp-rwj4-mv82"},{"ecosystem":"npm","fixed":["3.0.5"],"introduced":["1.0.0"],"last_affected":[],"package":"@diplodoc/search-extension","purl":"pkg:npm/%40diplodoc/search-extension","source":"GHSA-rjmp-rwj4-mv82"}],"prev":{"headline":"Memory corruption in musl","id":"CVE-2026-40200"},"products":["@diplodoc/search-extension"],"published":"2026-05-01","related":[],"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-05","vendors":["diplodoc-platform"]},"summary":"Stored XSS in @diplodoc/search-extension allows attackers to execute scripts via malicious Markdown titles, affecting users of the library.","url":"https://insights.sbomify.com/CVE-2026-40201/"}
