CVE-2026-54390 CRITICAL PATCH Act Now

Server-side template injection in JTL Shop 5.2.0 through 5.7.1 allows remote unauthenticated attackers to inject Smarty template syntax via unsanitized user input, exposing sensitive server-side values like database credentials and encryption keys. On versions 5.4.0 through 5.7.1, the flaw escalates to remote code execution by abusing registered Smarty modifiers (unserialize, file_get_contents) to drop a webshell and execute commands as the web server user. Publicly available exploit code exists via the Sansec research writeup, though no public exploit identified at time of analysis in CISA KEV.
