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-2026-123837/ (Markdown: https://insights.sbomify.com/CVE-2026-123837/index.md)","id":"CVE-2026-123837","markdown":"https://insights.sbomify.com/CVE-2026-123837/index.md","name":"CVE-2026-123837","record":{"aliases":["GHSA-f6xc-hpj3-cp3j"],"analysis":null,"analysis_generated_by":null,"assigner":"JetBrains","cpe":[{"name":"JetBrains IntelliJ IDEA","product":"intellij_idea","vendor":"jetbrains"}],"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-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"In JetBrains IntelliJ IDEA before 2026.3, \n2026.2.1 command injection was possible in untrusted projects via Tomcat run configurations on WSL","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"In JetBrains IntelliJ IDEA before 2026.3, 2026.2.1 command injection was possible in untrusted projects via Tomcat run configurations on WSL","id":"CVE-2026-123837","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"jetbrains:intellij_idea","products":["jetbrains:intellij_idea"],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"In JetBrains IntelliJ IDEA before 2026.3 code execution was possible in Safe Mode via UI Designer form file","id":"CVE-2026-123838"},"nickname":null,"packages":[],"prev":{"headline":"In JetBrains Datalore before 2026.4 workspace collaborators could obtain the owner's SSH private key via Git backup","id":"CVE-2026-123836"},"products":["IntelliJ IDEA"],"published":"2026-11-06","related":[{"cvss_score":10,"headline":"In JetBrains IntelliJ IDEA before 2026.2 unauthorized input injection was possible in a Remote Development session","id":"CVE-2026-64812","kev_date_added":null,"published":"2026-07-23"},{"cvss_score":10,"headline":"In JetBrains IntelliJ IDEA before 2026.2 unauthorized settings modification was possible in a Remote Development session","id":"CVE-2026-64813","kev_date_added":null,"published":"2026-07-23"},{"cvss_score":9.8,"headline":"In JetBrains IntelliJ IDEA before 2020.1, the license server could be resolved to an untrusted host in some cases.","id":"CVE-2020-11690","kev_date_added":null,"published":"2020-04-22"},{"cvss_score":9.8,"headline":"In several JetBrains IntelliJ IDEA Ultimate versions, an Application Server run configuration (for Tomcat, Jetty, Resin, or CloudBees) with","id":"CVE-2019-10104","kev_date_added":null,"published":"2019-07-03"},{"cvss_score":9.8,"headline":"In several JetBrains IntelliJ IDEA versions, a Spring Boot run configuration with the default setting allowed remote attackers to execute co","id":"CVE-2019-9186","kev_date_added":null,"published":"2019-07-03"},{"cvss_score":9.8,"headline":"In several JetBrains IntelliJ IDEA versions, creating remote run configurations of JavaEE application servers leads to saving a cleartext re","id":"CVE-2019-9823","kev_date_added":null,"published":"2019-07-03"},{"cvss_score":9.8,"headline":"In several versions of JetBrains IntelliJ IDEA Ultimate, creating Task Servers configurations leads to saving a cleartext unencrypted record","id":"CVE-2019-9873","kev_date_added":null,"published":"2019-07-03"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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-2026-123837/"}
