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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N","score":6.0},"cwes":["CWE-20","CWE-125","CWE-787"],"references":["https://trust.okta.com/security-advisories/improper-input-validation-in-the-okta-credential-provider-for-windows-cve-2026-78628"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:59:28.494260111+00:00"},"epss":{"cve":"CVE-2026-78628","score":0.00132,"percentile":0.02773,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
