Summary
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.
Risk Assessment
An attacker with a Contributor account can execute malicious scripts in visitors' browsers, hijacking sessions or performing actions on their behalf. This can lead to account takeover and spread of malicious content.
Recommendation
Update the VikRentCar plugin to a version later than 1.4.10 or disable it, then review Contributor-created content for injected scripts.
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-2026-111120High
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.
Original NVD description (English source)
The VikRentCar Car Rental Management System plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'className' parameter in all versions up to, and including, 1.4.10 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever 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 where only a raw double-quote is needed to break out, and block-comment JSON encoding of that quote is decoded back to a literal character by do_blocks() at render time.
