An attacker with low privileges who can control the URL option or culture-derived title values can supply a JavaScript URL or inject event-handler attributes. When a user interacts with an affected calendar, JavaScript can execute in the user's browser context and compromise the confidentiality and integrity of accessible data.","dates":{"published":"2026-10-15T14:12:05.941Z","modified":"2026-10-15T18:24:48.793Z","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":0.00162,"percentile":0.04959,"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":0.00162,"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":0.04959}],"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":0.04959}]},"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-79","name":"Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","description":"The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.","type":"weakness","status":"Stable","abstraction":"Base","likelihoodOfExploit":"High","url":"https://cwe.mitre.org/data/definitions/79.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":"≥ 2011.3.1007, < 2026.3.1015","noFixRecorded":false,"fixedIn":null}],"versionsText":"≥ 2011.3.1007, < 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":"≥ 2011.3.1007, < 2026.3.1015","noFixRecorded":false,"fixedIn":null}],"versionsText":"≥ 2011.3.1007, < 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-calendar-month-template-xss-cve-2026-106153","label":"www.telerik.com/kendo-jquery-ui/…","hostname":"www.telerik.com","tags":["Vendor Advisory"]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2026-10-15T14:12:05.941Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-10-15T18:24:48.793Z","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":"2026-10-21T12:21:19.155Z","stale":false,"partial":false}}
