bagisto has Server Side Template Injection (SSTI) in Product Description

  • Disclosed: 16.10.2025
  • Updated: 11.10.2026 10:22

Summary

Bagisto v2.3.7 is vulnerable to Server-Side Template Injection (SSTI) due to unsanitized user input being processed by the server-side templating engine when rendering product descriptions. This allows an attacker with product creation privileges to inject arbitrary template expressions that are evaluated by the backend — potentially leading to Remote Code Execution (RCE) on the server.

Details

In Bagisto, product descriptions are rendered through Laravel’s Blade templating engine in various front-end and admin views. The product description field is not sanitized or escaped before being passed to the view, which means user-supplied data can break out of the expected string context and execute arbitrary template code.

PoC

Create a product and enter the payload to the description. <img width="679" height="669" alt="image" src="https://github.com/user-attachments/assets/1e5dac3f-4043-4b31-98ed-f4346feb5477" /> Preview the page, observed that the template expressions were evaluated by the backend and displayed on the screen. <img width="1431" height="922" alt="image" src="https://github.com/user-attachments/assets/16f29c6e-05f4-40c4-9926-0c59e0a979c2" />

Impact

RCE potential: Attackers can execute arbitrary PHP code or system commands. Data breach: Read sensitive environment variables (.env), API keys, or database credentials. Defacement / persistence: Inject malicious scripts or backdoors in dynamic templates. Privilege escalation: If attackers have limited roles (e.g., product manager), they can compromise the entire application or host.
