VikRentCar WordPress plugin vulnerabilities

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.

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.

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.

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.
