DescriptionGitHub Advisory

Bagisto is an open source laravel eCommerce platform. Versions prior to 2.3.10 are vulnerable to server-side template injection via type parameter, which can lead to remote code execution or another exploitation. Version 2.3.10 fixes the issue.

AnalysisAI

Bagisto before 2.3.10 has a second server-side template injection vulnerability, this time via the type parameter. Like CVE-2026-21448, this enables remote code execution through the Blade template engine. Patch available in 2.3.10.

Technical ContextAI

The type parameter is passed to the Blade template engine without sanitization (CWE-1336), enabling server-side template injection. This is a separate injection point from CVE-2026-21448 (address fields), indicating a systemic lack of output encoding in Bagisto.

RemediationAI

Update to Bagisto 2.3.10 to fix both SSTI vulnerabilities (CVE-2026-21448 and CVE-2026-21450).
