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-2026-123321/ (Markdown: https://insights.sbomify.com/CVE-2026-123321/index.md)","id":"CVE-2026-123321","markdown":"https://insights.sbomify.com/CVE-2026-123321/index.md","name":"CVE-2026-123321","record":{"aliases":["GHSA-9jwp-fgw3-v68x"],"analysis":null,"analysis_generated_by":null,"assigner":"JetBrains","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-829","name":"Inclusion of Functionality from Untrusted Control Sphere"}],"description":"In JetBrains WebStorm before 2026.3, \n2026.2.3 code execution via Grunt and Gulp task loading was possible in untrusted projects","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 WebStorm before 2026.3, 2026.2.3 code execution via Grunt and Gulp task loading was possible in untrusted projects","id":"CVE-2026-123321","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 WebStorm before 2026.3, 2026.2.4 code execution was possible in untrusted projects via the Angular CLI schematics loader","id":"CVE-2026-123322"},"nickname":null,"packages":[],"prev":{"headline":"In JetBrains Toolbox App before 3.9 insufficient warning in the login dialog allowed connecting to a malicious server","id":"CVE-2026-123320"},"products":["WebStorm"],"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":"total"},"state":"PUBLISHED","updated":"2026-11-07","vendors":["JetBrains"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-123321/"}
