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.","state":0,"publishedAt":"2026-10-13T20:07:37.375+00:00","modifiedAt":"2026-10-14T19:27:28.784+00:00","affected":[{"ecosystem":"Vendor product","name":"Okta Credential Provider for Windows","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Okta\",\n                    \"product\": \"Okta Credential Provider for Windows\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThan\": \"1.4.6.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N","score":6,"severity":"MEDIUM"}],"references":["https://trust.okta.com/security-advisories/improper-input-validation-in-the-okta-credential-provider-for-windows-cve-2026-78628"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-78628","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-78628","identifiers":["CVE-2026-78628"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
