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-2026-86483 in the wild and no public exploit code.\n\nAffected product: JetBrains YouTrack. 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-2026-86483/ (Markdown: https://insights.sbomify.com/CVE-2026-86483/index.md)","id":"CVE-2026-86483","markdown":"https://insights.sbomify.com/CVE-2026-86483/index.md","name":"CVE-2026-86483","record":{"aliases":["GHSA-8ghm-r78p-92fx"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"JetBrains YouTrack","requires_auth":"low_privilege","summary":"Stored XSS in JetBrains YouTrack allows attackers to execute scripts via custom fields on Agile board cards, potentially leading to account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"JetBrains","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":"In JetBrains YouTrack before 2026.2.18634 stored XSS via a custom field on Agile board cards was possible","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Cross-site scripting in YouTrack","id":"CVE-2026-86483","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in YouTrack","id":"CVE-2026-86484"},"packages":[],"prev":{"headline":"Privilege escalation in YouTrack","id":"CVE-2026-86482"},"products":["YouTrack"],"published":"2026-09-07","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":"2026-09-08","vendors":["JetBrains"]},"summary":"Stored XSS in JetBrains YouTrack allows attackers to execute scripts via custom fields on Agile board cards, potentially leading to account takeover.","url":"https://insights.sbomify.com/CVE-2026-86483/"}
