An attacker who successfully exploited the vulnerability could attempt to force Outlook to load a local or remote message store (over SMB).\nTo exploit the vulnerability, the attacker could send a specially crafted email to a victim. Outlook would then attempt to open a pre-configured message store contained in the email upon receipt of the email.\nThis update addresses the vulnerability by ensuring Office fully validates incoming email formatting before processing message content.","published":"2019-08-14T21:15:18.000Z","lastModified":"2026-06-17T02:28:04.000Z","status":"Modified","sourceIdentifier":"secure@microsoft.com","cvss":{"version":"3.0","score":4.3,"severity":"MEDIUM","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N"},"cwe":["CWE-20"],"affected":["microsoft/office","microsoft/office 365 proplus","microsoft/outlook"],"epss":{"score":0.04423,"percentile":0.9131,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (4.42%).
