CVE-2026-103528: Smarty Template Code Injection in Thelia Email Templates

Sources read

1

Source agreement

Tam uyum

Evidence confidence

%53

Short explanation

Thelia 2.6.0 uses Smarty for email templates without properly restricting access to dangerous PHP functions. An authenticated administrator can inject malicious Smarty expressions via the messages configuration interface, allowing command execution and file operations with web process privileges.

Why does it matter?

This vulnerability allows an authenticated administrator to achieve remote code execution (RCE), execute arbitrary OS commands, and perform file read and write operations on the underlying server.

What should be done?

  • Follow official vendor advisories
  • Restrict access to configuration interfaces
  • Await vendor updates for fixed versions
Note on uncertainty

The sources give limited detail on some technical conditions. Review the chain of evidence below before deciding how to act.

Show the technical text from the sources

Thelia 2.6.0 uses Smarty for email templates without properly restricting access to dangerous PHP functions. An authenticated administrator can inject malicious Smarty expressions into email templates via the messages configuration interface, and when the template is previewed or rendered, functions such as system(), exec(), file_put_contents(), and file_get_contents() can be executed with the privileges of the web process. This allows arbitrary OS command execution, file read/write operations, and RCE on the underlying server.
