The chosen value was not sufficiently sanitized before processing it at the user interface, allowing for indirect cross-site scripting attacks. Accounts that were temporarily taken over could be configured to trigger persistent code execution, allowing an attacker to build a foothold. Sanitization is in place for product names now. No publicly available exploits are known.\n\n","published":"2023-11-02T14:15:11.000Z","lastModified":"2026-06-17T05:43:22.000Z","status":"Modified","sourceIdentifier":"security@open-xchange.com","cvss":{"version":"3.1","score":5.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N"},"cwe":["CWE-79"],"affected":["open-xchange/ox guard"],"epss":{"score":0.00383,"percentile":0.31187,"date":"2026-10-22","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.38%).
