Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-89078 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- gitlab (Bitnami): affected from 19.2.0; fixed in 19.2.7, 19.3.3, 19.4.1\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-2026-89078/ (Markdown: https://insights.sbomify.com/CVE-2026-89078/index.md)","id":"CVE-2026-89078","markdown":"https://insights.sbomify.com/CVE-2026-89078/index.md","name":"CVE-2026-89078","record":{"aliases":["ALPINE-CVE-2026-89078","BELL-CVE-2026-89078","BIT-gitlab-2026-89078","DEBIAN-CVE-2026-89078","GHSA-9chr-4x58-948m","MINI-2r4q-gf4h-9gcg","MINI-5pv8-2p8x-q8cg","MINI-69pq-498x-p9q9","MINI-6q43-929g-pphm","MINI-7v9m-753v-p7v4","MINI-94fq-29h6-f32p","MINI-gh3w-6r6j-4m4j","MINI-gvx6-c84c-9p8m","MINI-h638-37fv-48r8","MINI-h7w5-xggx-8fj2","MINI-m9qh-v6p6-mrwx","MINI-w5r5-89x5-48px","MINI-xcx7-v9xp-cggg"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"GitLab CI/CD","requires_auth":"low_privilege","summary":"An authenticated user can execute arbitrary code on the GitLab server by exploiting a double free vulnerability in CI/CD configuration parsing.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitLab","cpe":[{"product":"gitlab","vendor":"gitlab"}],"cvss":{"score":9.9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-415","name":"Double Free"}],"description":"GitLab has remediated an issue in GitLab CE/EE affecting all versions from 19.2 before 19.2.7, 19.3 before 19.3.3, and 19.4 before 19.4.1 that under certain conditions could have allowed an authenticated user to execute arbitrary code on the GitLab server due to a double free issue when parsing a specially crafted regular expression in a CI/CD configuration.","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":"Double Free in GitLab","id":"CVE-2026-89078","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"gitlab:gitlab","products":["gitlab:gitlab"],"type":"use_after_free","year":"2026"},"n_packages":1,"n_references":3,"next":{"headline":"Privilege escalation in Theme My Login","id":"CVE-2026-89079"},"packages":[{"ecosystem":"Bitnami","fixed":["19.2.7","19.3.3","19.4.1"],"introduced":["19.2.0","19.3.0","19.4.0"],"last_affected":[],"package":"gitlab","purl":"pkg:bitnami/gitlab","source":"BIT-gitlab-2026-89078"}],"prev":{"headline":"MOVEit Transfer Identity validation flaw in SFTP authentication","id":"CVE-2026-89077"},"products":["GitLab"],"published":"2026-09-23","related":[{"cvss_score":10,"headline":"GitLab Community Edition and Enterprise Edition Integer Overflow or Wraparound","id":"CVE-2026-97229","kev_date_added":"2026-10-29","published":"2026-10-13"},{"cvss_score":10,"headline":"GitLab Community Edition and Enterprise Edition Path Traversal","id":"CVE-2026-85706","kev_date_added":"2026-09-11","published":"2026-09-12"},{"cvss_score":10,"headline":"GitLab Community and Enterprise Editions Improper Access Control","id":"CVE-2023-7028","kev_date_added":"2024-05-01","published":"2024-01-12"},{"cvss_score":10,"headline":"GitLab Community and Enterprise Editions Remote Code Execution","id":"CVE-2021-22205","kev_date_added":"2021-11-03","published":"2021-04-23"},{"cvss_score":6.8,"headline":"GitLab Community and Enterprise Editions Server-Side Request Forgery (SSRF)","id":"CVE-2021-39935","kev_date_added":"2026-02-03","published":"2021-12-13"},{"cvss_score":6.8,"headline":"GitLab Server-Side Request Forgery (SSRF)","id":"CVE-2021-22175","kev_date_added":"2026-02-18","published":"2021-06-11"},{"cvss_score":10,"headline":"Integer Overflow or Wraparound in GitLab","id":"CVE-2026-110264","kev_date_added":null,"published":"2026-10-22"}],"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":"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":"total"},"state":"PUBLISHED","updated":"2026-09-25","vendors":["GitLab"]},"summary":"An authenticated user can execute arbitrary code on the GitLab server by exploiting a double free vulnerability in CI/CD configuration parsing.","url":"https://insights.sbomify.com/CVE-2026-89078/"}
