{"schema":"threatline.record/2","record":{"id":"CVE-2026-78628","aliases":[],"summary":"Improper Input Validation in the Okta Credential Provider for Windows","details":"The Okta Credential Provider for Windows does not validate a serialized credential buffer before interpreting it as a Kerberos logon structure. The buffer size and packed string offsets are not checked. Processing a malformed buffer can cause the credential provider process to terminate unexpectedly or lead to out-of-bounds memory reads and writes, which may result in the disclosure of adjacent process memory into local system logs.","categories":["Identity & access"],"product":"Okta Credential Provider for Windows","vendor":"Okta","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-78628","source_modified_at":"2026-10-14T19:27:28.784Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Okta Credential Provider for Windows","vendor":"Okta","versions":[{"version":"0","status":"affected","lessThan":"1.4.6.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-78628","source_modified_at":"2026-10-14T19:27:28.784Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Okta Credential Provider for Windows","ecosystem":null},"version":"1.4.6.0","basis":"first unaffected version stated in the CVE record"}],"cvss":6,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00132,"percentile":0.02541,"score_date":"2026-10-23"},"published_at":"2026-10-13T20:07:37.375Z","modified_at":"2026-10-14T19:27:28.784Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-78628","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-14T19:27:28.784Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-78628","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://trust.okta.com/security-advisories/improper-input-validation-in-the-okta-credential-provider-for-windows-cve-2026-78628"}],"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":"2026-10-14T19:27:16.578491Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-14T19:27:28.784Z","content_hash":"5682fafc3f54d91842f5b3727f763b18a5a54068a135fb31bc2aea1b25d46ee1"}}
