The VikRentCar Car Rental Management System plugin for WordPress is vulnerable to blind SQL Injection via the 'catid' parameter in all versions up to, and including, 1.4.10 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. A Contributor-level user can store a malicious block via the REST API in a pending post and trigger server-side rendering by previewing that post, bypassing wpmagicquotes since the attribute is sourced from postcontent via parseblocks rather than a superglobal.

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. wpksespost() 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 doblocks() at render time.

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 condtextupdatetmpl function. This makes it possible for unauthenticated attackers to write arbitrary PHP code to the plugin's executable template files such as site/helpers/emailtmpl.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 PHPOPEN/PHPCLOSE placeholder expansion and cleanPHPSourceCode() logic explicitly reverse both sanitizetextfield 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.

The VikBooking Hotel Booking Engine & PMS plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'attachments[name]' Parameter in all versions up to, and including, 1.8.15 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The VikBooking Hotel Booking Engine & PMS WordPress plugin before 1.7.2 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfilteredhtml capability is disallowed (for example in multisite setup).

The VikBooking Hotel Booking Engine & PMS plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.7.2. This is due to missing or incorrect nonce validation on the 'save' function. This makes it possible for unauthenticated attackers to change plugin access privileges via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. Successful exploitation allows attackers with subscriber-level privileges and above to upload arbitrary files on the affected site's server which may make remote code execution possible.

The VikBooking Hotel Booking Engine & PMS WordPress plugin before 1.6.8's access control mechanism fails to properly restrict access to its settings, permitting any users that can access a menu to manipulate requests and perform unauthorized actions such as editing, renaming or deleting (categories for example) despite initial settings prohibiting such access. This vulnerability resembles broken access control, enabling unauthorized users to modify critical VikBooking Hotel Booking Engine & PMS WordPress plugin before 1.6.8 configurations.

The VikBooking Hotel Booking Engine & PMS WordPress plugin before 1.6.8 allows direct access to menus, allowing an authenticated user with subscriber privileges or above, to bypass authorization and access settings of the VikBooking Hotel Booking Engine & PMS WordPress plugin before 1.6.8's they shouldn't be allowed to.

The VikBooking Hotel Booking Engine & PMS WordPress plugin before 1.5.8 does not escape various settings before outputting them in attributes, which could allow high privilege users such as admin to perform Cross-Site Scripting attacks even when unfilteredhtml is disallowed

The VikBooking Hotel Booking Engine & PMS WordPress plugin before 1.5.8 does not have CSRF check in place when adding a tracking campaign, and does not escape the campaign fields when outputting them In attributes. As a result, attackers could make a logged in admin add tracking campaign with XSS payloads in them via a CSRF attack
