An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-9806 in the wild and no public exploit code.\n\nAffected product: misp cti-transmute. 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-2026-9806/ (Markdown: https://insights.sbomify.com/CVE-2026-9806/index.md)","id":"CVE-2026-9806","markdown":"https://insights.sbomify.com/CVE-2026-9806/index.md","name":"CVE-2026-9806","record":{"aliases":["GHSA-w9rm-vvqp-qq3h"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"CTI Transmute","requires_auth":"none","summary":"Stored XSS in CTI Transmute allows attackers to inject JavaScript via malicious convert names, executing code in authenticated users' browsers.","user_interaction":"not_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:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N/S:N/RE:L/U:Clear","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A stored cross-site scripting (XSS) vulnerability exists in the notification panel of CTI Transmute in versions prior to the patched release. Notification messages containing user-controlled convert names were rendered in the notification bell dropdown using innerHTML without adequate sanitization. An attacker able to create or influence a convert name that is included in a notification could inject arbitrary JavaScript, which would execute in the browser of an authenticated user when they opened the notification panel. Successful exploitation could allow the attacker to perform actions in the victim's session or access information available to the application in the browser context. The issue was remediated by constructing notification elements through DOM methods and assigning notification message content via textContent instead of innerHTML. This vulnerability was only present on a development branch.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-08-02","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-08-02T19:43:20Z","kind":"github_poc","ref":"https://github.com/aj2108/CVE-2026-9806","stars":0,"title":"CVE-2026-9806 is a Stored Cross-Site Scripting (Stored XSS) vulnerability affecting CTI Transmute versions prior to the patched release."}],"tier":"poc_unverified"},"has_fix":false,"headline":"Stored Cross-Site Scripting (XSS) in CTI Transmute Notification Panel via Malicious Convert Names","id":"CVE-2026-9806","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Incorrect Authorization in GitLab","id":"CVE-2026-9807"},"packages":[],"prev":{"headline":"FMTSWriteUseIntelLib: FMTS SMM IHISI Buffer Overflow","id":"CVE-2026-9805"},"products":["cti-transmute"],"published":"2026-05-28","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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-28","vendors":["misp"]},"summary":"Stored XSS in CTI Transmute allows attackers to inject JavaScript via malicious convert names, executing code in authenticated users' browsers.","url":"https://insights.sbomify.com/CVE-2026-9806/"}
