The MasterStudy LMS WordPress plugin from 1.9 before 3.7.50 does not verify that a course a member asks to enrol in is covered by their membership plan, nor that the plan identifier submitted with the request is one they actually hold, allowing any member to enrol themselves into restricted paid courses outside their plan and beyond the number of courses it entitles them to.

The MasterStudy LMS WordPress Plugin WordPress plugin before 3.7.50 does not validate one of its display-style settings before using it to build a template path, allowing users with the Contributor role and above to include and execute arbitrary local PHP files on the server. An equivalent path was corrected in an earlier release and this one was not, so the issue persists in versions the earlier advisory reports as fixed.

The MasterStudy LMS WordPress Plugin WordPress plugin before 3.7.50 does not perform any capability or nonce checks on an administrative maintenance action, allowing any authenticated user, such as a subscriber, to trigger it and create published content on the site attributed to their own account.

The MasterStudy LMS WordPress Plugin WordPress plugin before 3.7.50 does not check whether user registration is enabled on the site before creating an account through one of its front-end registration flows, allowing unauthenticated users to create accounts, and be logged into them, on sites where registration has been deliberately disabled.

The MasterStudy LMS WordPress Plugin WordPress plugin before 3.7.50 does not verify that a user is enrolled in a course before recording lesson completions against it, allowing any authenticated user, such as a subscriber, to create course progress records for courses they have no access to.

The MasterStudy LMS WordPress Plugin WordPress plugin before 3.7.50 does not properly sanitise and restrict HTML in user-submitted content before storing it and rendering it to other users, allowing users with subscriber-level accounts and above to perform stored HTML injection, such as embedding iframes, that can be leveraged for phishing and content spoofing against other users viewing the content.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in StylemixThemes Motors allows Blind SQL Injection.

This issue affects Motors: from n/a through 1.4.109.

Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in StylemixThemes Motors allows PHP Local File Inclusion.

This issue affects Motors: from n/a through 1.4.109.

Missing Authorization vulnerability in StylemixThemes MasterStudy LMS Pro allows Accessing Functionality Not Properly Constrained by ACLs.

This issue affects MasterStudy LMS Pro: from n/a before 4.7.16.

The Motors – Car Dealership & Classified Listings plugin for WordPress is vulnerable to Payment Bypass via insecure user meta update in all versions up to, and including, 1.4.103 This is due to the stmsaveuserextrafields() function updating sensitive user meta fields from POST data without verifying that the current user should have permission to modify those fields. The function hooks into the 'personaloptionsupdate' action and only checks currentusercan('edituser', $userid), which passes for any user editing their own profile. This makes it possible for authenticated attackers, with Subscriber-level access and above, to set their stmpaymentstatus to 'completed', bypassing the PayPal payment verification and gaining access to paid Dealer membership features without completing any transaction.

The MasterStudy LMS WordPress Plugin for Online Courses and Education plugin for WordPress is vulnerable to Time-based Blind SQL Injection via the 'order' and 'orderby' parameters in the /lms/stm-lms/order/items REST API endpoint in versions up to and including 3.7.25. This is due to insufficient input sanitization combined with a design flaw in the custom Query builder class that allows unquoted SQL injection in ORDER BY clauses. When the Query builder detects parentheses in the sortby parameter, it treats the value as a SQL function and directly concatenates it into the ORDER BY clause without any quoting. While escsql() is applied to escape quotes and backslashes, this cannot prevent ORDER BY injection when the values themselves are not wrapped in quotes in the resulting SQL statement. This makes it possible for authenticated attackers, with subscriber-level access and above, to append arbitrary SQL queries via the ORDER BY clause to extract sensitive information from the database including user credentials, session tokens, and other confidential data through time-based blind SQL injection techniques.

The Cost Calculator Builder plugin for WordPress is vulnerable to Unauthenticated Payment Status Bypass in all versions up to, and including, 3.6.9 only when used in combination with Cost Calculator Builder PRO. This is due to the completepayment AJAX action being registered via wpajaxnopriv, making it accessible to unauthenticated users, and the complete() function only verifying a nonce without checking user capabilities or order ownership. Since nonces are exposed to all visitors via window.ccbnonces in the page source, any unauthenticated attacker can mark any order's payment status as "completed" without actual payment.

The Motors – Car Dealership & Classified Listings Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Phone Number parameter in all versions up to, and including, 1.4.63 due to insufficient input sanitization and output escaping.

The Motors – Car Dealership & Classified Listings Plugin plugin for WordPress is vulnerable to arbitrary plugin installations due to a missing capability check in the mvlsetupwizardinstallplugin() function in all versions up to, and including, 1.4.64.
