{"schemaVersion":3,"id":"CVE-2026-106160","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"In Progress® Kendo® UI for jQuery prior to 2026.3.1015, Model.accept passes server-response keys to kendo.setter without guarding against unsafe object paths containing __proto__, constructor, or prototype. An attacker who can supply data accepted by an affected model can modify object prototype attributes and influence application behavior, potentially compromising the confidentiality and integrity of application data. The impact depends on how the application uses the modified objects, including in server-side JavaScript scenarios. The earliest affected version has not been confirmed. This issue is fixed in version 2026.3.1015.","dates":{"published":"2026-10-15T13:24:33.068Z","modified":"2026-10-15T18:26:30.515Z","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":0.00175,"percentile":0.06556,"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":0.00175,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00175,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00175,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00175,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00175,"percentile":0.06556}],"last30":[{"date":"2026-10-16T00:00:00.000Z","score":0.00175,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00175,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00175,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00175,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00175,"percentile":0.06556}]},"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-1321","name":"Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution')","description":"The product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype.","type":"weakness","status":"Incomplete","abstraction":"Variant","likelihoodOfExploit":null,"url":"https://cwe.mitre.org/data/definitions/1321.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":"≥ 2023.1.117, < 2026.3.1015","noFixRecorded":false,"fixedIn":null}],"versionsText":"≥ 2023.1.117, < 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":"≥ 2023.1.117, < 2026.3.1015","noFixRecorded":false,"fixedIn":null}],"versionsText":"≥ 2023.1.117, < 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-model-accept-prototype-pollution-cve-2026-106160","label":"www.telerik.com/kendo-jquery-ui/…","hostname":"www.telerik.com","tags":["Vendor Advisory"]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2026-10-15T13:24:33.068Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-10-15T18:26:30.515Z","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":"2026-10-21T04:03:05.653Z","stale":false,"partial":false}}
