{"schemaVersion":3,"id":"CVE-2026-106151","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"In Progress® Kendo® UI for jQuery versions starting with 2012.2.710 and prior to 2026.3.1015, the Validator decodes validation messages from data-msg-* attributes and parses the resulting text as HTML. 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.","dates":{"published":"2026-10-15T14:11:08.537Z","modified":"2026-10-15T18:12:49.751Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":5.4,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","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","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","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","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00178,"percentile":0.0696,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-16T00:00:00.000Z","score":0.00162,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00162,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00162,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00162,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00162,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00178,"percentile":0.0696}],"last30":[{"date":"2026-10-16T00:00:00.000Z","score":0.00162,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00162,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00162,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00162,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00162,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00178,"percentile":0.0696}]},"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-80","name":"Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS)","description":"The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special characters such as \"<\", \">\", and \"&\" that could be interpreted as web-scripting elements when they are sent to a downstream component that processes web pages.","type":"weakness","status":"Incomplete","abstraction":"Variant","likelihoodOfExploit":"High","url":"https://cwe.mitre.org/data/definitions/80.html"}],"affected":[{"vendor":"progress software","product":"kendo ui for jquery","name":"Kendo UI for jQuery","label":"kendo ui for jquery","ecosystem":null,"cpePart":"a","purl":null,"purlType":null,"versions":[{"text":"≥ 2012.2.710, < 2026.3.1015","noFixRecorded":false,"fixedIn":null}],"versionsText":"≥ 2012.2.710, < 2026.3.1015","eol":null,"hubHref":"/vendor/progress_software/kendo_ui_for_jquery"},{"vendor":"progress","product":"kendo_ui","name":"kendo ui","label":"kendo_ui","ecosystem":null,"cpePart":"a","purl":null,"purlType":null,"versions":[{"text":"≥ 2012.2.710, < 2026.3.1015","noFixRecorded":false,"fixedIn":null}],"versionsText":"≥ 2012.2.710, < 2026.3.1015","eol":null,"hubHref":"/vendor/progress/kendo_ui"}],"affectedCount":2,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://www.telerik.com/kendo-jquery-ui/documentation/knowledge-base/kb-security-validator-message-xss-cve-2026-106151","label":"www.telerik.com/kendo-jquery-ui/…","hostname":"www.telerik.com","tags":["Vendor Advisory"]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2026-10-15T14:11:08.537Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-10-15T18:12:49.751Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":22,"level":"low","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-22T04:47:10.184Z","stale":false,"partial":false}}
