An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-5262 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- gitlab (Bitnami): affected from 16.1.0; fixed in 18.9.6, 18.10.4, 18.11.1\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-2026-5262/ (Markdown: https://insights.sbomify.com/CVE-2026-5262/index.md)","id":"CVE-2026-5262","markdown":"https://insights.sbomify.com/CVE-2026-5262/index.md","name":"CVE-2026-5262","record":{"aliases":["BIT-gitlab-2026-5262","GHSA-g9pv-f88j-p6rr"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"GitLab","requires_auth":"none","summary":"An unauthenticated attacker can access tokens in the Storybook development environment via XSS, requiring specific conditions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitLab","cpe":[{"product":"gitlab","vendor":"gitlab"}],"cvss":{"score":8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"GitLab has remediated an issue in GitLab CE/EE affecting all versions from 16.1.0 before 18.9.6, 18.10 before 18.10.4, and 18.11 before 18.11.1 that under certain conditions could have allowed an unauthenticated user to access tokens in the Storybook development environment due to improper input validation.","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":"Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in GitLab","id":"CVE-2026-5262","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"gitlab:gitlab","products":["gitlab:gitlab"],"type":"xss","year":"2026"},"n_packages":1,"n_references":3,"next":{"headline":"URI nameConstraints not enforced in ConfirmNameConstraints()","id":"CVE-2026-5263"},"packages":[{"ecosystem":"Bitnami","fixed":["18.9.6","18.10.4","18.11.1"],"introduced":["16.1.0","18.10.0","18.11.0"],"last_affected":[],"package":"gitlab","purl":"pkg:bitnami/gitlab","source":"BIT-gitlab-2026-5262"}],"prev":{"headline":"Shandong Hoteam InforCenter PLM BaseHandler.ashx uploadFileToIIS unrestricted upload","id":"CVE-2026-5261"},"products":["GitLab"],"published":"2026-04-22","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":"2026-04-22","vendors":["GitLab"]},"summary":"An unauthenticated attacker can access tokens in the Storybook development environment via XSS, requiring specific conditions.","url":"https://insights.sbomify.com/CVE-2026-5262/"}
