An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2024-27199 in the wild since at least 20 Apr 2026, including in ransomware campaigns.\n\nAffected product: Jetbrains Teamcity. 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-2024-27199/ (Markdown: https://insights.sbomify.com/CVE-2024-27199/index.md)","id":"CVE-2024-27199","markdown":"https://insights.sbomify.com/CVE-2024-27199/index.md","name":"CVE-2024-27199","record":{"aliases":["GHSA-m7gg-q7qj-3r2r"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"CI/CD server","requires_auth":"none","summary":"Attackers can exploit path traversal in TeamCity to perform limited administrative actions, requiring an upgrade to the latest version.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"JetBrains","cpe":[{"product":"teamcity","vendor":"jetbrains"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"},{"id":"CWE-23","name":"Relative Path Traversal"}],"description":"In JetBrains TeamCity before 2023.11.4 path traversal allowing to perform limited admin actions  was possible","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2024/CVE-2024-27199.yaml","stars":null,"title":"TeamCity \u003c 2023.11.4 - Authentication Bypass"}],"tier":"exploited"},"has_fix":null,"headline":"JetBrains TeamCity Relative Path Traversal","id":"CVE-2024-27199","indexable":true,"kev":{"dateAdded":"2026-04-20","dueDate":"2026-05-04","knownRansomwareCampaignUse":"Known","product":"TeamCity","requiredAction":"Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.","vendorProject":"JetBrains","vulnerabilityName":"JetBrains TeamCity Relative Path Traversal Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"jetbrains:teamcity","products":["jetbrains:teamcity"],"type":"path_traversal","year":"2024"},"n_packages":0,"n_references":2,"next":{"headline":"Improper access control in some Intel(R) Granulate(TM) software before version 4.30.1 may allow a authenticated user to potentially enable e","id":"CVE-2024-27200"},"packages":[],"prev":{"headline":"JetBrains TeamCity Authentication Bypass","id":"CVE-2024-27198"},"products":["TeamCity"],"published":"2024-03-04","related":[{"cvss_score":9.8,"headline":"JetBrains TeamCity Deserialization of Untrusted Data","id":"CVE-2026-63077","kev_date_added":"2026-08-05","published":"2026-07-27"},{"cvss_score":9.8,"headline":"JetBrains TeamCity Authentication Bypass","id":"CVE-2024-27198","kev_date_added":"2024-03-07","published":"2024-03-04"},{"cvss_score":9.8,"headline":"JetBrains TeamCity Authentication Bypass","id":"CVE-2023-42793","kev_date_added":"2023-10-04","published":"2023-09-19"},{"cvss_score":9.8,"headline":"Auth bypass in TeamCity","id":"CVE-2024-23917","kev_date_added":null,"published":"2024-02-06"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2022-24331","kev_date_added":null,"published":"2022-02-25"},{"cvss_score":9.8,"headline":"XML external entity in n/a","id":"CVE-2022-24340","kev_date_added":null,"published":"2022-02-25"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":"yes","exploitation":"active","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-21","vendors":["JetBrains"]},"summary":"Attackers can exploit path traversal in TeamCity to perform limited administrative actions, requiring an upgrade to the latest version.","url":"https://insights.sbomify.com/CVE-2024-27199/"}
