An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-30504 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-2021-30504/ (Markdown: https://insights.sbomify.com/CVE-2021-30504/index.md)","id":"CVE-2021-30504","markdown":"https://insights.sbomify.com/CVE-2021-30504/index.md","name":"CVE-2021-30504","record":{"aliases":["GHSA-887c-6389-89qh"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IntelliJ IDEA","requires_auth":"none","summary":"Attackers can cause a denial of service in JetBrains IntelliJ IDEA via unbounded resource allocation, requiring an upgrade to resolve.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"intellij_idea","vendor":"jetbrains"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"In JetBrains IntelliJ IDEA before 2021.1, DoS was possible because of unbounded resource allocation.","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":"Denial of service in n/a","id":"CVE-2021-30504","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"jetbrains:intellij_idea","products":["jetbrains:intellij_idea"],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in Chrome","id":"CVE-2021-30506"},"packages":[],"prev":{"headline":"Command injection in n/a","id":"CVE-2021-30503"},"products":["n/a"],"published":"2021-05-11","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"Attackers can cause a denial of service in JetBrains IntelliJ IDEA via unbounded resource allocation, requiring an upgrade to resolve.","url":"https://insights.sbomify.com/CVE-2021-30504/"}
