An attacker who can modify a validation message can cause HTML that was correctly escaped in the page attribute to become active markup, including event handlers, when the user triggers validation. Successful exploitation can execute JavaScript in a user's browser and compromise the confidentiality and integrity of data accessible to the affected application. This issue is fixed in version 2026.3.1015.","published":"2026-10-15T15:17:22.000Z","lastModified":"2026-10-20T19:38:49.000Z","status":"Analyzed","sourceIdentifier":"security@progress.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-80"],"affected":["progress/kendo ui"],"epss":{"score":0.00178,"percentile":0.07275,"date":"2026-10-26","history":[{"date":"2026-10-16","score":0.00162,"percentile":0.04934}]},"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 (0.18%).
