An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-42921 in the wild and no public exploit code.\n\nAffected product: JetBrains Toolbox App. 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-2025-42921/ (Markdown: https://insights.sbomify.com/CVE-2025-42921/index.md)","id":"CVE-2025-42921","markdown":"https://insights.sbomify.com/CVE-2025-42921/index.md","name":"CVE-2025-42921","record":{"aliases":["GHSA-32gj-564x-3982"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"JetBrains Toolbox App","requires_auth":"none","summary":"Missing SSH host key verification in JetBrains Toolbox App allows attackers to bypass security checks and potentially intercept connections.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"JetBrains","cpe":[{"product":"toolbox","vendor":"jetbrains"}],"cvss":{"score":4.2,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-297","name":"Improper Validation of Certificate with Host Mismatch"}],"description":"In JetBrains Toolbox App before 2.6 host key verification was missing in SSH plugin","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":"Security feature bypass in Toolbox App","id":"CVE-2025-42921","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Insecure File Operations vulnerability in SAP NetWeaver AS Java (Deploy Web Service)","id":"CVE-2025-42922"},"packages":[],"prev":{"headline":"Cross-Site Scripting (XSS) vulnerability in SAP Supplier Relationship Management","id":"CVE-2025-42920"},"products":["Toolbox App"],"published":"2025-04-17","related":[{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2020-25207","kev_date_added":null,"published":"2020-11-16"},{"cvss_score":8.3,"headline":"In JetBrains Toolbox App before 2.6 command injection in SSH plugin was possible","id":"CVE-2025-43012","kev_date_added":null,"published":"2025-04-17"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2020-25013","kev_date_added":null,"published":"2020-11-16"},{"cvss_score":7.5,"headline":"Security feature bypass in n/a","id":"CVE-2020-15827","kev_date_added":null,"published":"2020-08-08"},{"cvss_score":7.3,"headline":"Privilege escalation in n/a","id":"CVE-2019-18368","kev_date_added":null,"published":"2019-10-31"},{"cvss_score":6.9,"headline":"Weak cryptography in Toolbox App","id":"CVE-2025-43013","kev_date_added":null,"published":"2025-04-17"},{"cvss_score":6.1,"headline":"Security feature bypass in Toolbox App","id":"CVE-2025-43014","kev_date_added":null,"published":"2025-04-17"}],"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":"partial"},"state":"PUBLISHED","updated":"2025-04-17","vendors":["JetBrains"]},"summary":"Missing SSH host key verification in JetBrains Toolbox App allows attackers to bypass security checks and potentially intercept connections.","url":"https://insights.sbomify.com/CVE-2025-42921/"}
