Loading vulnerability…
CVE-2026-41452 is a missing-authentication vulnerability in Krayin CRM 2.2.4's installer middleware. A request marked as an XMLHttpRequest bypasses the installer-state redirect check, allowing an unauthenticated caller to invoke administrative setup logic after installation. The setup operation performs an unauthenticated update-or-insert against the primary administrator record and accepts attacker-controlled administrator name, email address, and password values.

The repository contains a README and a 452-byte Bash proof-of-concept script, poc.sh. The script accepts a target URL and attacker-selected username, email, and password, then uses curl to POST those values to the Krayin CRM installation endpoint. It adds X-Requested-With: XMLHttpRequest, which the accompanying documentation claims bypasses the CanInstall middleware's normal installation-state redirect behavior. The resulting request is intended to invoke an unauthenticated update-or-insert operation against administrator record ID 1, replacing the primary administrator credentials and permitting account takeover. The script reports success only if the response contains the character '1', making its success validation unreliable. It is a standalone operational PoC rather than a framework module; supplied values are inserted into form data without URL encoding.
