Vulnerability from github – Published: 2025-04-28 21:30 – Updated: 2025-04-28 21:30

Details

Enterprise Protection contains an improper input validation vulnerability in attachment defense that allows an unauthenticated remote attacker to bypass attachment scanning security policy by sending a malicious S/MIME attachment with an opaque signature. When opened by a recipient in a downstream email client, the malicious attachment could cause partial loss of integrity and confidentiality to their system.

Severity

6.1 (Medium)
