Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-86487 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-2026-86487/ (Markdown: https://insights.sbomify.com/CVE-2026-86487/index.md)","id":"CVE-2026-86487","markdown":"https://insights.sbomify.com/CVE-2026-86487/index.md","name":"CVE-2026-86487","record":{"aliases":["GHSA-8g79-9363-v5v2"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Issue tracking software","requires_auth":"low_privilege","summary":"Read-only users can modify whiteboard content in JetBrains YouTrack due to missing authorization checks on WebSocket messages.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"JetBrains","cpe":[],"cvss":{"score":3.1,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"In JetBrains YouTrack before 2026.2.18634 a crafted WebSocket message allowed read-only whiteboard users to modify canvas content","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":"Missing authorization in YouTrack","id":"CVE-2026-86487","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in YouTrack","id":"CVE-2026-86488"},"packages":[],"prev":{"headline":"Auth bypass in YouTrack","id":"CVE-2026-86486"},"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":"Read-only users can modify whiteboard content in JetBrains YouTrack due to missing authorization checks on WebSocket messages.","url":"https://insights.sbomify.com/CVE-2026-86487/"}
