{"id":"CVE-2026-81814","summary":"Flowintel Stored XSS in Calendar via Malicious Case Title","details":"Affected versions of Flowintel render calendar event titles using innerHTML. Because those titles are derived from case titles, a user able to create or modify a case title could store HTML or script-capable content that is later interpreted by the browser when another user views the calendar.\n\n\nThe fix changes:\n\n\ntitleEl.innerHTML = arg.event.title\n\n\nto:\n\n\ntitleEl.textContent = arg.event.title || ''\n\nand similarly stops using innerHTML for the static download icon.\n\nVersion impacted =\u003e3.3.0","modified":"2026-08-30T03:30:40.009303223Z","published":"2026-08-27T12:48:39.314Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/81xxx/CVE-2026-81814.json","cna_assigner":"CIRCL","cwe_ids":["CWE-79"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/81xxx/CVE-2026-81814.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-81814"},{"type":"FIX","url":"https://github.com/flowintel/flowintel/commit/f224438eb495e6b0d4e465eb7f40ab771bbfdb76.patch"},{"type":"PACKAGE","url":"https://github.com/flowintel/flowintel"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/flowintel/flowintel","events":[{"introduced":"0"},{"fixed":"f224438eb495e6b0d4e465eb7f40ab771bbfdb76"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"last_affected":"3.3.0"}]}}],"versions":["3.3.0","3.2.0","3.1.0","3.0.0","2.3.0","2.2.1","2.1.1","2.1.0","2.0.0","1.6.2","1.6.1","1.6.0","1.5.0","1.4.1","1.4.0","1.3.1","1.3.0","1.2.0","1.1.0","1.0.0","0.8.0","0.7.0","0.6.0","0.5.1","0.5.0","0.4.0","0.3.0","0.2.1","0.2.0","0.1.0","0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-81814.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N"}]}
