Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-86498 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-2026-86498/ (Markdown: https://insights.sbomify.com/CVE-2026-86498/index.md)","id":"CVE-2026-86498","markdown":"https://insights.sbomify.com/CVE-2026-86498/index.md","name":"CVE-2026-86498","record":{"aliases":["GHSA-jgfw-8cqw-4r27"],"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":"Attackers can modify linked entities in JetBrains YouTrack via PUT requests without having the required update permission.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"JetBrains","cpe":[],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"In JetBrains YouTrack before 2025.3.160480, \n2026.1.14047 pUT requests on link sub-resources allowed modification linked entities without update permission","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-2026-86498","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":"Information disclosure in YouTrack","id":"CVE-2026-86499"},"packages":[],"prev":{"headline":"Information disclosure in YouTrack","id":"CVE-2026-86497"},"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":"Attackers can modify linked entities in JetBrains YouTrack via PUT requests without having the required update permission.","url":"https://insights.sbomify.com/CVE-2026-86498/"}
