A critical missing-authentication vulnerability tracked as CVE-2026-41452 affects Krayin CRM 2.2.4 and allows remote, unauthenticated attackers to seize the primary administrator account. The flaw resides in the product's installer middleware, where a crafted HTTP POST request using the X-Requested-With: XMLHttpRequest header can bypass the CanInstall middleware redirect check and reach the install/api/admin-config-setup endpoint.
Researchers said the vulnerable endpoint performs an unauthenticated updateOrInsert against a hardcoded administrator user ID, letting an attacker set arbitrary administrator name, email, and password values and gain full access to CRM data. The issue has been rated Critical, with reported scores of CVSS 3.1 9.8 and CVSS 4.0 9.3; recommended mitigations include updating Krayin CRM, applying vendor patches, and removing or properly securing the installer after deployment.
