{"id":"CVE-2026-60008","summary":"Gitea Jupyter notebook UI redress through CSS class injection","details":"Gitea's Jupyter notebook renderer inserts the notebook's language_info.name metadata into a CSS class attribute while disabling sanitization and rendering directly in the main document without an iframe sandbox. A malicious repository notebook can supply multiple CSS classes that create a viewport-covering overlay and intercept clicks when another user views it. The reported impact is UI redress; script execution was not demonstrated.","aliases":["GHSA-7452-653r-6gp8"],"modified":"2026-10-15T02:47:43.995555666Z","published":"2026-10-14T14:28:31.043Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/60xxx/CVE-2026-60008.json","cna_assigner":"Gitea","cwe_ids":["CWE-1021","CWE-79"]},"references":[{"type":"ADVISORY","url":"https://blog.gitea.com/release-of-1.27.2/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/60xxx/CVE-2026-60008.json"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/38793"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/38795"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.2"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-7452-653r-6gp8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-60008"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/go-gitea/gitea","events":[{"introduced":"73e0e442988704487b285d59f7494a85229e41e2"},{"last_affected":"a62dfffbe7d3a454c2f2d3c4b2788ba432724a5f"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"1.27.0"},{"last_affected":"1.27.1"}]}}],"versions":["v1.27.1","v1.27.0","v1.27.0-rc0","v1.28.0-dev","v1.27.0-dev"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-60008.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:N"}]}
