CVE-2026-90944: Missing Authentication for Critical Function in krayin laravel-crm
Krayin laravel-crm versions up to 2.2.6 have a missing authentication vulnerability on the POST /admin/mail/inbound-parse endpoint. This allows unauthenticated attackers to inject arbitrary emails into the CRM inbox by sending crafted RFC 2822 messages with forged sender information and headers. The vulnerability enables attackers to insert emails with any subject and body, including replies to existing conversation threads.
AI Analysis
Technical Summary
CVE-2026-90944 describes a missing authentication vulnerability in Krayin laravel-crm through version 2.2.6. The POST /admin/mail/inbound-parse endpoint is exposed without requiring authentication, permitting unauthenticated attackers to inject arbitrary emails into the CRM inbox. Attackers can craft RFC 2822-compliant email messages with forged sender details and headers to insert emails with arbitrary content, including replies to existing conversations. This flaw could allow manipulation of email data within the CRM system.
Potential Impact
Unauthenticated attackers can inject arbitrary emails into the CRM inbox, potentially disrupting communication workflows, injecting misleading or malicious content, or confusing users by forging sender information and email threads. The CVSS 4.0 score is 8.8 (high severity), reflecting the network attack vector, no required privileges or user interaction, and high impact on integrity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the /admin/mail/inbound-parse endpoint through network controls or authentication proxies to prevent unauthenticated access.
