Summary
The VikRentCar plugin for WordPress in versions up to and including 1.4.8 is vulnerable to cross-site request forgery (CSRF) in the condtext_update_tmpl function due to missing nonce validation. This allows unauthenticated attackers to write arbitrary PHP code to the plugin's template files and achieve remote code execution if they can trick an administrator into clicking a link.
Risk Assessment
An attacker could achieve arbitrary PHP code execution on the server, taking control of the site. However, this requires administrator interaction, reducing but not eliminating the threat.
Recommendation
Update the VikRentCar plugin to a version later than 1.4.8. Additionally, implement CSRF protections and regularly review administrator permissions.
Other vulnerabilities in VikRentCar WordPress plugin
See all- CVE-2026-116548High
The VikRentCar Car Rental Management System plugin for WordPress in versions up to and including 1.4.10 is vulnerable to Stored Cross-Site Scripting via the 'optionals' parameter. An unauthenticated attacker can inject arbitrary web scripts that execute when a user accesses an injected page.
- CVE-2026-116750Medium
The VikRentCar Car Rental Management System plugin for WordPress in all versions up to and including 1.4.10 is vulnerable to blind SQL injection via the 'catid' parameter due to insufficient escaping of the user-supplied parameter and lack of sufficient preparation of the existing SQL query. An authenticated attacker with Contributor-level access can append additional SQL queries to extract sensitive information from the database by storing a malicious block via the REST API in a pending post and triggering server-side rendering through preview.
- CVE-2026-116749Medium
The VikRentCar Car Rental Management System plugin for WordPress in all versions up to and including 1.4.10 is vulnerable to stored cross-site scripting via the 'className' parameter due to insufficient input sanitization and output escaping. An authenticated attacker with Contributor-level access can inject arbitrary web scripts that execute when a user accesses an injected page; wp_kses_post() applied at save time does not neutralize the payload because the injection lands in an HTML-attribute context and the block-comment JSON encoding of the quote is decoded by do_blocks() at render time.
Original NVD description (English source)
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.
