HIGH 8.8

DescriptionCVE.org

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.

AnalysisAI

Missing authentication on Krayin CRM's admin mail ingest route lets any remote, unauthenticated attacker POST crafted RFC 2822 messages to /admin/mail/inbound-parse and plant arbitrary emails — including forged replies stitched into existing conversation threads — in victim CRM inboxes on every release through 2.2.6. VulnCheck reports proof-of-concept exploit code (SSVC Exploitation: PoC) and the attack is fully automatable, but the issue is not listed in CISA KEV, so active in-the-wild abuse is not confirmed; the CVSS v4.0 base score is 8.8, driven by high integrity impact with no confidentiality impact and only limited availability impact.
