CVE-2026-90944 Details
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.
A vulnerability in Krayin CRM versions through 2.2.6 allows unauthenticated attackers to inject arbitrary emails into the CRM inbox via the POST /admin/mail/inbound-parse endpoint. This endpoint is exposed without authentication, as it is explicitly removed from CSRF protection and the authentication middleware is stripped away. Attackers can send crafted RFC 2822 messages with forged sender details and headers, including replies to existing conversation threads. The injected emails are processed and stored in the inbox, where they are visible to all authenticated users.
Users are advised to update to Krayin CRM version 2.2.6 or later, where this vulnerability has been addressed.
