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-2026-75045 in the wild and no public exploit code.\n\nAffected product: Jetbrains Youtrack. 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-2026-75045/ (Markdown: https://insights.sbomify.com/CVE-2026-75045/index.md)","id":"CVE-2026-75045","markdown":"https://insights.sbomify.com/CVE-2026-75045/index.md","name":"CVE-2026-75045","record":{"aliases":["GHSA-68v9-f358-h326"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"JetBrains YouTrack","requires_auth":"none","summary":"An unauthenticated attacker can download database backups by exploiting a shared draft signature vulnerability in JetBrains YouTrack.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"JetBrains","cpe":[{"product":"youtrack","vendor":"jetbrains"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"In JetBrains YouTrack before 2025.3.156085, \n2026.1.13913, \n2026.2.18112 an unauthenticated attacker could download database backups via shared draft signature","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-10-19","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-10-19T20:32:55Z","kind":"github_poc","ref":"https://github.com/LHeiakim/CVE-2026-75045-PoC","stars":0,"title":"CVE-2026-75045 - JetBrains YouTrack unauthenticated database backup download via shared draft signature (CVSS 9.1)"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Auth bypass in YouTrack","id":"CVE-2026-75045","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"jetbrains:youtrack","products":["jetbrains:youtrack"],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in YouTrack","id":"CVE-2026-75046"},"packages":[],"prev":{"headline":"Missing authorization in YouTrack","id":"CVE-2026-75044"},"products":["YouTrack"],"published":"2026-08-17","related":[{"cvss_score":10,"headline":"Auth bypass in YouTrack","id":"CVE-2026-62422","kev_date_added":null,"published":"2026-07-14"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2022-24442","kev_date_added":null,"published":"2022-02-25"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2021-43185","kev_date_added":null,"published":"2021-11-09"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2021-25770","kev_date_added":null,"published":"2021-02-03"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2019-12850","kev_date_added":null,"published":"2019-07-03"},{"cvss_score":9.8,"headline":"Server-side request forgery in n/a","id":"CVE-2019-12852","kev_date_added":null,"published":"2019-07-03"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2019-12866","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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-18","vendors":["JetBrains"]},"summary":"An unauthenticated attacker can download database backups by exploiting a shared draft signature vulnerability in JetBrains YouTrack.","url":"https://insights.sbomify.com/CVE-2026-75045/"}
