{"schemaVersion":3,"id":"CVE-2026-60008","aliases":[],"status":"published","duplicateOf":null,"title":"Gitea Jupyter notebook UI redress through CSS class injection","description":"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.","dates":{"published":"2026-10-14T14:28:31.043Z","modified":"2026-10-14T15:26:34.451Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":3.5,"severity":"low","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":3.5,"severity":"low","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":3.5,"severity":"low","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.0037,"percentile":0.29768,"severity":"low","asOf":"2026-10-22T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-15T00:00:00.000Z","score":0.0037,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.0037,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.0037,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.0037,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.0037,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.0037,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.0037,"percentile":null},{"date":"2026-10-22T00:00:00.000Z","score":0.0037,"percentile":0.29768}],"last30":[{"date":"2026-10-15T00:00:00.000Z","score":0.0037,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.0037,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.0037,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.0037,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.0037,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.0037,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.0037,"percentile":null},{"date":"2026-10-22T00:00:00.000Z","score":0.0037,"percentile":0.29768}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-79","name":"Improper
