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-2026-123336/ (Markdown: https://insights.sbomify.com/CVE-2026-123336/index.md)","id":"CVE-2026-123336","markdown":"https://insights.sbomify.com/CVE-2026-123336/index.md","name":"CVE-2026-123336","record":{"aliases":["GHSA-gv5f-529c-m3rx"],"analysis":null,"analysis_generated_by":null,"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:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"In JetBrains YouTrack before 2026.2.19728 the attachment size limit could be bypassed via AI assistant thread conversion","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":"In JetBrains YouTrack before 2026.2.19728 the attachment size limit could be bypassed via AI assistant thread conversion","id":"CVE-2026-123336","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"In JetBrains YouTrack before 2026.2.19656 users without update permission could change issue visibility","id":"CVE-2026-123337"},"nickname":null,"packages":[],"prev":{"headline":"In JetBrains YouTrack before 2026.2.19562, 2026.1.14137, 2025.3.169041 missing authorization allowed attaching tags to any issue via the tag","id":"CVE-2026-123335"},"products":["YouTrack"],"published":"2026-11-06","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":"2026-11-06","vendors":["JetBrains"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-123336/"}
