{"schemaVersion":3,"id":"CVE-2026-106159","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"In Progress® Kendo® UI for jQuery versions starting with 2022.3.1109 and prior to 2026.3.1015, ToolBar ButtonGroup button URLs are concatenated into an unquoted href attribute after URL sanitization. An attacker who can control a button URL can supply an otherwise allowed HTTPS URL containing whitespace and additional attributes, including an event handler, and execute JavaScript in a user's browser when the affected button is interacted with. Successful exploitation can compromise the confidentiality and integrity of data accessible to the affected application. This issue is fixed in version 2026.3.1015.","dates":{"published":"2026-10-15T13:23:40.132Z","modified":"2026-10-15T18:26:53.924Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":4.7,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:H/PR:N/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":4.7,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:H/PR:N/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":4.7,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00157,"percentile":0.04425,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-16T00:00:00.000Z","score":0.00157,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00157,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00157,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00157,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00157,"percentile":0.04425}],"last30":[{"date":"2026-10-16T00:00:00.000Z","score":0.00157,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00157,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00157,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00157,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00157,"percentile":0.04425}]},"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":"≥ 2022.3.1109, < 2026.3.1015","noFixRecorded":false,"fixedIn":null}],"versionsText":"≥ 2022.3.1109, < 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":"≥ 2022.3.1109, < 2026.3.1015","noFixRecorded":false,"fixedIn":null}],"versionsText":"≥ 2022.3.1109, < 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-toolbar-buttongroup-url-xss-cve-2026-106159","label":"www.telerik.com/kendo-jquery-ui/…","hostname":"www.telerik.com","tags":["Vendor Advisory"]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2026-10-15T13:23:40.132Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-10-15T18:26:53.924Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":19,"level":"low","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-21T03:40:32.365Z","stale":false,"partial":false}}
