Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-1403 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- gitlab (Bitnami): affected from 11.7.0; fixed in 18.8.9, 18.9.5, 18.10.3\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-2026-1403/ (Markdown: https://insights.sbomify.com/CVE-2026-1403/index.md)","id":"CVE-2026-1403","markdown":"https://insights.sbomify.com/CVE-2026-1403/index.md","name":"CVE-2026-1403","record":{"aliases":["BIT-gitlab-2026-1403","GHSA-6w5v-7h2v-438h","UBUNTU-CVE-2026-1403"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"GitLab","requires_auth":"low_privilege","summary":"An authenticated user can cause denial of service to Sidekiq workers by importing improperly structured CSV files in GitLab.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitLab","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"GitLab has remediated an issue in GitLab CE/EE affecting all versions from 11.7 before 18.8.9, 18.9 before 18.9.5, and 18.10 before 18.10.3 that when importing CSV files could have allowed an authenticated user to cause denial of service to Sidekiq workers due to improper validation of CSV file structure.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Allocation of Resources Without Limits or Throttling in GitLab","id":"CVE-2026-1403","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":1,"n_references":2,"next":{"headline":"Ultimate Member \u003c= 2.11.1 - Reflected Cross-Site Scripting via Filter Parameters","id":"CVE-2026-1404"},"packages":[{"ecosystem":"Bitnami","fixed":["18.8.9","18.9.5","18.10.3"],"introduced":["11.7.0","18.9.0","18.10.0"],"last_affected":[],"package":"gitlab","purl":"pkg:bitnami/gitlab","source":"BIT-gitlab-2026-1403"}],"prev":{"headline":"Allocation of Resources Without Limits or Throttling in GitLab","id":"CVE-2026-1402"},"products":["GitLab"],"published":"2026-10-07","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-10-07","vendors":["GitLab"]},"summary":"An authenticated user can cause denial of service to Sidekiq workers by importing improperly structured CSV files in GitLab.","url":"https://insights.sbomify.com/CVE-2026-1403/"}
