Unauthenticated email injection via unsigned inbound webhook
Published Sep 14, 2026 · Updated Sep 14, 2026
Authentication bypass in Bagisto Krayin CRM 2.2.6 and earlier allows remote attackers to inject forged email into the CRM inbox. The inbound-parse route removes the user middleware, bypasses URL sanitization for AJAX requests, and passes unsigned RFC 2822 input to the parser for inbox storage. No account is required; a network caller can forge sender, subject, body, and thread headers, creating deceptive messages and false CRM records.
