An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-49381 in the wild and no public exploit code.\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-2026-49381/ (Markdown: https://insights.sbomify.com/CVE-2026-49381/index.md)","id":"CVE-2026-49381","markdown":"https://insights.sbomify.com/CVE-2026-49381/index.md","name":"CVE-2026-49381","record":{"aliases":["GHSA-mhr7-j6qx-58mw"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"CI/CD server","requires_auth":"high_privilege","summary":"Stored XSS in the SAML login page allows attackers to execute scripts in victim browsers, potentially leading to session hijacking or data theft.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"JetBrains","cpe":[{"product":"teamcity","vendor":"jetbrains"}],"cvss":{"score":3.4,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"In JetBrains TeamCity before 2026.1 stored XSS on the SAML login page was possible","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":"Cross-site scripting in TeamCity","id":"CVE-2026-49381","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"jetbrains:teamcity","products":["jetbrains:teamcity"],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Code injection in IntelliJ IDEA","id":"CVE-2026-49382"},"packages":[],"prev":{"headline":"Open redirect in TeamCity","id":"CVE-2026-49380"},"products":["TeamCity"],"published":"2026-05-29","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":7.3,"headline":"JetBrains TeamCity Relative Path Traversal","id":"CVE-2024-27199","kev_date_added":"2026-04-20","published":"2024-03-04"},{"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":"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":"2026-05-29","vendors":["JetBrains"]},"summary":"Stored XSS in the SAML login page allows attackers to execute scripts in victim browsers, potentially leading to session hijacking or data theft.","url":"https://insights.sbomify.com/CVE-2026-49381/"}
