## Technical details

The plugin's condtext_update_tmpl function lacks proper nonce validation, enabling cross-site request forgery. An unauthenticated attacker can craft a malicious request that writes arbitrary PHP code to template files (e.g., site/helpers/email_tmpl.php), which are later included during execution. The injected payload bypasses sanitization because the plugin's placeholder expansion logic (using __PHP_OPEN__/__PHP_CLOSE__) and cleanPHPSourceCode() function explicitly reverse both sanitize_text_field() and HTML encoding, restoring literal PHP tags before writing to disk.
