It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2026-100256 and fix it if it is affected.\n\nWhat it is: CVE-2026-100256 is a high-severity code injection vulnerability in Jetbrains Intellij Idea, published on 30 Sep 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-100256 in the wild and no public exploit code.\n\nAffected product: Jetbrains Intellij Idea. 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-2026-100256/ (Markdown: https://insights.sbomify.com/CVE-2026-100256/index.md)","id":"CVE-2026-100256","markdown":"https://insights.sbomify.com/CVE-2026-100256/index.md","name":"CVE-2026-100256","record":{"aliases":["GHSA-x2cm-2gq8-g82v"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"IntelliJ IDEA IDE","requires_auth":"none","summary":"Attackers can execute arbitrary code via Structural Search script constraints in untrusted projects using JetBrains IntelliJ IDEA.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"JetBrains","cpe":[{"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-829","name":"Inclusion of Functionality from Untrusted Control Sphere"}],"description":"In JetBrains IntelliJ IDEA before 2026.2.3 rCE via Structural Search script constraints 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":false,"headline":"Code injection in IntelliJ IDEA","id":"CVE-2026-100256","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"jetbrains:intellij_idea","products":["jetbrains:intellij_idea"],"type":"code_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Server-side request forgery in YouTrack","id":"CVE-2026-100257"},"packages":[],"prev":{"headline":"Auth bypass in TeamCity","id":"CVE-2026-100255"},"products":["IntelliJ IDEA"],"published":"2026-09-30","related":[{"cvss_score":10,"headline":"Missing authorization in IntelliJ IDEA","id":"CVE-2026-64812","kev_date_added":null,"published":"2026-07-23"},{"cvss_score":10,"headline":"Missing authorization in IntelliJ IDEA","id":"CVE-2026-64813","kev_date_added":null,"published":"2026-07-23"},{"cvss_score":9.8,"headline":"Server-side request forgery in n/a","id":"CVE-2020-11690","kev_date_added":null,"published":"2020-04-22"},{"cvss_score":9.8,"headline":"Misconfiguration in n/a","id":"CVE-2019-10104","kev_date_added":null,"published":"2019-07-03"},{"cvss_score":9.8,"headline":"Misconfiguration in n/a","id":"CVE-2019-9186","kev_date_added":null,"published":"2019-07-03"},{"cvss_score":9.8,"headline":"Hardcoded credentials in n/a","id":"CVE-2019-9823","kev_date_added":null,"published":"2019-07-03"},{"cvss_score":9.8,"headline":"Hardcoded credentials in n/a","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":"2026-10-01","vendors":["JetBrains"]},"summary":"Attackers can execute arbitrary code via Structural Search script constraints in untrusted projects using JetBrains IntelliJ IDEA.","url":"https://insights.sbomify.com/CVE-2026-100256/"}
