{"schema":"threatline.record/2","record":{"id":"CVE-2026-106155","aliases":[],"summary":"Stored Cross-site Scripting (XSS) in Telerik Report Server Web Report Viewers","details":"In Progress® Telerik® Report Server prior to version 12.2.26.1007, a stored cross-site scripting vulnerability in the shared reporting engine allows an authenticated report author to embed javascript: or vbscript: URLs in report navigation actions or HTML text box links. When another user views the malicious report and the embedded navigation is triggered, attacker-controlled script can execute in the web report viewer's origin. In a multi-user Report Server deployment, this can enable privilege escalation by performing actions in a higher-privilege user's authenticated session, including an administrator's session.","categories":["Unclassified"],"product":"Telerik Report Server","vendor":"Progress Software","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-106155","source_modified_at":"2026-10-09T18:03:02.317Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Telerik Report Server","vendor":"Progress Software","versions":[{"status":"affected","version":"0","lessThan":"12.2.26.1007","versionType":"custom"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-106155","source_modified_at":"2026-10-09T18:03:02.317Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Telerik Report Server","ecosystem":null},"version":"12.2.26.1007","basis":"first unaffected version stated in the CVE record"}],"cvss":8.9,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00199,"percentile":0.09202,"score_date":"2026-10-23"},"published_at":"2026-10-09T07:07:57.817Z","modified_at":"2026-10-09T18:03:02.317Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-106155","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-09T18:03:02.317Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-106155","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.telerik.com/report-server/documentation/knowledge-base/kb-security-improper-neutralization-of-input-cve-2026-106155","tags":["vendor-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-09T18:02:51.071557Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-09T18:03:02.317Z","content_hash":"f9cce664095438681a8229b9ef06deb47b1ebc32a21ff4f3ecb8c6bf6c60794a"}}
