CVE-2026-21446 Bagisto Missing Authentication on Installer API Endpoints

What is CVE-2026-21446?

CVE-2026-21446 is a high-severity missing authorization vulnerability in bagisto, published on 2 Jan 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

Bagisto is an open source laravel eCommerce platform. In versions on the 2.3 branch prior to 2.3.10, API routes remain active even after initial installation is complete. The underlying API endpoints (`/install/api/*`) are directly accessible and exploitable without any authentication. An attacker can bypass the Ib installer entirely by calling the API endpoints directly. This allows any unauthenticated attacker to create admin accounts, modify application configurations, and potentially overwrite existing data. Version 2.3.10 fixes the issue.

Weakness: CWE-306
