{"schemaVersion":3,"id":"CVE-2026-106145","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"In Progress® Telerik® Report Server prior to version 12.2.26.1007, incorrect privilege assignment in the service-agent SignalR hub allows an authenticated user, including a low-privilege or guest account with a valid bearer token, to register as a trusted service agent. On the next server settings-synchronization event, the rogue agent receives storage settings and encryption private keys. This privilege escalation enables disclosure of protected secrets, including stored data-source credentials and connection strings, and allows agent impersonation and interference with task dispatch.","dates":{"published":"2026-10-09T07:03:34.351Z","modified":"2026-10-09T18:03:22.258Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.1,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":7.1,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.1,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00145,"percentile":0.03411,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-09T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00145,"percentile":0.03411}],"last30":[{"date":"2026-10-09T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00145,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00145,"percentile":0.03411}]},"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-266","name":"Incorrect Privilege Assignment","description":"A product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that actor.","type":"weakness","status":"Draft","abstraction":"Base","likelihoodOfExploit":null,"url":"https://cwe.mitre.org/data/definitions/266.html"}],"affected":[{"vendor":"progress software","product":"telerik report server","name":"Telerik Report Server","label":"telerik report server","ecosystem":null,"cpePart":"a","purl":null,"purlType":null,"versions":[{"text":"< 12.2.26.1007","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 12.2.26.1007","eol":null,"hubHref":"/vendor/progress_software/telerik_report_server"}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://www.telerik.com/report-server/documentation/knowledge-base/kb-security-incorrect-privilege-assignment-cve-2026-106145","label":"www.telerik.com/report-server/…","hostname":"www.telerik.com","tags":["Vendor Advisory"]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2026-10-09T07:03:34.351Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-10-09T18:03:22.258Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":28,"level":"medium","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-21T07:58:32.900Z","stale":false,"partial":false}}
