Description
Krayin CRM through 2.2.6 exposes the POST /admin/mail/inbound-parse endpoint without authentication, allowing unauthenticated attackers to inject arbitrary emails into the CRM inbox. Attackers can supply crafted RFC 2822 messages with forged sender information and headers to insert emails with any subject and body, including replies to existing conversation threads.
