CVE-2026-111120

Full vulnerability record from the local CVENow database.

Description

The VikRentCar Car Rental Management System plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.4.8. This is due to missing or incorrect nonce validation on the condtext_update_tmpl function. This makes it possible for unauthenticated attackers to write arbitrary PHP code to the plugin's executable template files such as site/helpers/email_tmpl.php, which are later include()d by loadEmailTemplate() and loadPdfTemplate(), achieving remote code execution on the server via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. The injected PHP payload bypasses sanitization because the plugin's own __PHP_OPEN__/__PHP_CLOSE__ placeholder expansion and cleanPHPSourceCode() logic explicitly reverse both sanitize_text_field filtering and saveHTML() HTML-encoding, restoring a literal <?php...?> payload to live PHP before it is written to disk. Successful exploitation additionally requires an action by an administrator — the attacker cannot trigger the vulnerability on their own.
