It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-25758 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-2021-25758/ (Markdown: https://insights.sbomify.com/CVE-2021-25758/index.md)","id":"CVE-2021-25758","markdown":"https://insights.sbomify.com/CVE-2021-25758/index.md","name":"CVE-2021-25758","record":{"aliases":["GHSA-m3hg-xq69-26f2"],"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":"low_privilege","summary":"Local attackers can execute arbitrary code via insecure deserialization of the workspace model in JetBrains IntelliJ IDEA.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"intellij_idea","vendor":"jetbrains"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"In JetBrains IntelliJ IDEA before 2020.3, potentially insecure deserialization of the workspace model could lead to local code execution.","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":"Deserialization in n/a","id":"CVE-2021-25758","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"jetbrains:intellij_idea","products":["jetbrains:intellij_idea"],"type":"deserialization","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Missing authorization in n/a","id":"CVE-2021-25759"},"packages":[],"prev":{"headline":"Open redirect in n/a","id":"CVE-2021-25757"},"products":["n/a"],"published":"2021-02-03","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":"Local attackers can execute arbitrary code via insecure deserialization of the workspace model in JetBrains IntelliJ IDEA.","url":"https://insights.sbomify.com/CVE-2021-25758/"}
