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-2026-94373 in the wild and no public exploit code.\n\nAffected product: MISP. 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-2026-94373/ (Markdown: https://insights.sbomify.com/CVE-2026-94373/index.md)","id":"CVE-2026-94373","markdown":"https://insights.sbomify.com/CVE-2026-94373/index.md","name":"CVE-2026-94373","record":{"aliases":["GHSA-6m7x-x7f7-6wjc"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"MISP threat sharing","requires_auth":"low_privilege","summary":"Attackers can inject malicious scripts into MISP contextual menus via innerHTML, potentially hijacking sessions or stealing data from authenticated users.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CIRCL","cpe":[],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"MISP contains a DOM-based cross-site scripting (XSS) vulnerability in the contextual menu JavaScript component. The ContextualMenu class populates HTML \u003coption\u003e elements by assigning user-controllable values to the innerHTML property. Because innerHTML parses and renders HTML markup, any untrusted string supplied as the option text (value.text or value) is interpreted as live DOM content rather than plain text. An attacker who can influence the data rendered in the contextual menu can inject arbitrary HTML or JavaScript that executes in the victim's browser within the MISP application origin. This may allow session hijacking, data exfiltration, or unauthorized actions performed on behalf of the authenticated user.\n\nVersion affected: \u003c2.5.47","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":"MISP DOM-based Cross-Site Scripting via innerHTML in Contextual Menu","id":"CVE-2026-94373","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in MISP","id":"CVE-2026-94374"},"packages":[],"prev":{"headline":"Stored Cross-Site Scripting via Unescaped Galaxy Cluster Tag Names in MISP Default Theme Galaxies Index","id":"CVE-2026-94372"},"products":["MISP"],"published":"2026-09-21","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-09-21","vendors":["MISP"]},"summary":"Attackers can inject malicious scripts into MISP contextual menus via innerHTML, potentially hijacking sessions or stealing data from authenticated users.","url":"https://insights.sbomify.com/CVE-2026-94373/"}
