{"id":"CVE-2026-111120","published":"2026-10-28T07:16:46.837","lastModified":"2026-10-28T07:16:46.837","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.","cvssScore":8.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","cwes":["CWE-352"],"vendors":[],"products":[],"references":[{"url":"https://plugins.trac.wordpress.org/browser/vikrentcar/tags/1.4.8/admin/controller.php#L9558","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/vikrentcar/tags/1.4.8/admin/controller.php#L9609","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/vikrentcar/tags/1.4.8/admin/helpers/conditional_rules.php#L1003","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/vikrentcar/tags/1.4.8/admin/helpers/conditional_rules.php#L654","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/vikrentcar/tags/1.4.8/admin/helpers/conditional_rules.php#L765","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/vikrentcar/tags/1.4.8/site/helpers/lib.vikrentcar.php#L2685","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3755596%40vikrentcar&new=3755596%40vikrentcar","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/36f84246-6658-407a-88dd-4b99a784e682?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
