The WP Hotel Booking plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'check_in_date' parameter in all versions up to, and including, 2.3.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The LearnPress – WordPress LMS Plugin for Create and Sell Online Courses plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 4.4.1 via the check_answer. This makes it possible for unauthenticated attackers to extract the correct-answer markers, full option lists, explanations, and question content for any quiz question on the site — including questions belonging to paid courses the attacker is not enrolled in.

The WP Hotel Booking plugin for WordPress is vulnerable to Insufficient Verification of Data Authenticity in all versions up to, and including, 2.3.1. This is due to the `web_hook_process_paypal_standard()` IPN handler selecting its PayPal validation endpoint from the attacker-controlled `$_REQUEST['test_ipn']` parameter, force-upgrading any `pending` transaction to `completed` when `test_ipn=1`, and omitting post-verification checks on `receiver_email`, `mc_currency`, and `txn_id` uniqueness after receiving a `VERIFIED` response from PayPal. This makes it possible for unauthenticated attackers to mark arbitrary hotel bookings as fully paid without submitting genuine payment to the merchant — either by routing IPN validation through PayPal's sandbox using a free sandbox account, or by replaying a previously verified IPN from a nominal payment to an attacker-controlled PayPal account. An attacker requires only a free PayPal sandbox account (or any PayPal account) to obtain a `VERIFIED` response; no site credentials or special configuration are needed.

The WP Hotel Booking plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'check_in_date' and 'check_out_date' parameters in all versions up to, and including, 2.3.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The LearnPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'class_wrapper_form' shortcode attribute in versions up to, and including, 4.4.0. This is due to insufficient input sanitization and output escaping in the FilterCourseTemplate::sections() method at line 98, where the attacker-controlled attribute is inserted into an HTML class attribute via sprintf('<form class="%s">', $class_wrapper_form) without esc_attr() escaping. The FilterCourseShortcode::render() handler does not apply shortcode_atts() filtering, so raw user attributes flow directly through do_action('learn-press/filter-courses/layout', $data) into the template. 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.

The LearnPress – WordPress LMS Plugin for Create and Sell Online Courses plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.3.9.1 via the 'userId' parameter due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with subscriber-level access and above, to view the course enrollment progress and completion data belonging to any instructor or administrator account on the site. This IDOR does not apply when the target user is a regular subscriber, as the guard correctly blocks cross-subscriber access; exploitation is limited to cases where the victim user holds the LP_TEACHER_ROLE or administrator role.

The LearnPress – WordPress LMS Plugin for Create and Sell Online Courses plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 4.3.6 via the 'return_type' parameter. This makes it possible for unauthenticated attackers to extract sensitive data including the plaintext post_password of password-protected courses and the full post_content, post_author, and post_name of unpublished draft, private, and pending courses via the unrestricted SELECT * fallback query. Exploitation requires supplying both c_status=all (to bypass the publish-only post_status WHERE clause) and return_type=json (to prevent the safe DISTINCT(ID) AS ID field override) in a single unauthenticated request to the /wp-json/lp/v1/courses/archive-course endpoint.

The LearnPress – Backup & Migration Tool plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 4.1.4 via deserialization of untrusted input . This makes it possible for authenticated attackers, with administrator-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.

The LearnPress – Backup & Migration Tool plugin for WordPress is vulnerable to Arbitrary File Read via Directory Traversal in all versions up to, and including, 4.1.4 via the 'import-user-file' parameter parameter. This makes it possible for authenticated attackers, with administrator-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information.

Missing Authorization vulnerability in ThimPress Thim Core allows Exploiting Incorrectly Configured Access Control Security Levels. This issue affects Thim Core: from n/a through 2.3.3.

Missing Authorization vulnerability leading to code execution after installing malicious vulnerable plugin in ThimPress Thim Core. This issue affects Thim Core: from n/a through 2.3.3.

The LearnPress – WordPress LMS Plugin for Create and Sell Online Courses plugin for WordPress is vulnerable to payment bypass through user-controlled key in all versions up to, and including, 4.3.5. This is due to improper handling of user-supplied request parameters in the REST API endpoint, which passes the unsanitized parameter array to the add_to_cart() function where array_merge() allows attacker-controlled values to overwrite hardcoded defaults. This makes it possible for authenticated attackers, with subscriber-level access and above, to enroll in any paid course entirely free of charge by supplying a quantity value of zero, which causes the order total to calculate as $0 and bypasses all payment gateway requirements.

The FundPress – WordPress Donation Plugin for WordPress is vulnerable to authorization bypass in versions up to and including 2.0.8. This is due to missing authorization and nonce verification in the donate_action_status() AJAX handler, which is registered to be accessible to unauthenticated users via wp_ajax_nopriv. The function only validates that the schema parameter equals 'donate-ajax' and that the required POST parameters are present, but fails to verify user capabilities, nonce tokens, or donation ownership. This makes it possible for unauthenticated attackers to modify the status of any donation by providing its ID (which are sequential integers and easily enumerable), allowing them to mark donations as completed, pending, cancelled, or any arbitrary status, potentially triggering email notifications and related side effects.

The LearnPress plugin for WordPress is vulnerable to unauthorized data deletion due to a missing capability check on the `delete_question_answer()` function in all versions up to, and including, 4.3.2.8. The plugin exposes a `wp_rest` nonce in public frontend HTML (`lpData`) to unauthenticated visitors, and uses that nonce as the only security gate for the `lp-load-ajax` AJAX dispatcher. The `delete_question_answer` action has no capability or ownership check. This makes it possible for unauthenticated attackers to delete any quiz answer option by sending a crafted POST request with a publicly available nonce.

The LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'skin' attribute of the learn_press_courses shortcode in all versions up to and including 4.3.3. This is due to insufficient input sanitization and output escaping on the 'skin' shortcode attribute. The attribute value is used directly in an sprintf() call that generates HTML (class attribute and data-layout attribute) without any esc_attr() 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.

Authentication Bypass Using an Alternate Path or Channel vulnerability in ThimPress LearnPress – Sepay Payment learnpress-sepay-payment allows Authentication Abuse.This issue affects LearnPress – Sepay Payment: from n/a through <= 4.0.0.

The LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to unauthorized deletion of quiz question answers due to a missing capability check in the delete_question_answer() function of the EditQuestionAjax class in all versions up to, and including, 4.3.2.8. The AbstractAjax::catch_lp_ajax() dispatcher verifies a wp_rest nonce but performs no current_user_can() check, and the QuestionAnswerModel::delete() method only validates minimum answer counts without checking user capabilities. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete answer options from any quiz question on the site.

Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in ThimPress BuilderPress builderpress allows PHP Local File Inclusion.This issue affects BuilderPress: from n/a through <= 2.0.1.

The Thim Kit for Elementor – Pre-built Templates & Widgets for Elementor plugin for WordPress is vulnerable to unauthorized access of data due to a missing validation checks on the 'thim-ekit/archive-course/get-courses' REST endpoint callback function in all versions up to, and including, 1.3.7. This makes it possible for unauthenticated attackers to disclose private or draft LearnPress course content by supplying post_status in the params_url payload.

The LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to unauthorized email notification triggering due to missing capability checks on all 10 functions in the SendEmailAjax class in all versions up to, and including, 4.3.2.8. The AbstractAjax::catch_lp_ajax() dispatcher verifies a wp_rest nonce but performs no current_user_can() check before dispatching to handler functions. The wp_rest nonce is embedded in the frontend JavaScript for all authenticated users. This makes it possible for authenticated attackers, with Subscriber-level access and above, to trigger arbitrary email notifications to admins, instructors, and users, enabling email flooding, social engineering, and impersonation of admin decisions regarding instructor requests.

The LearnPress Export Import – WordPress extension for LearnPress plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'delete_migrated_data' function in all versions up to, and including, 4.1.0. This makes it possible for unauthenticated attackers to delete course that have been migrated from Tutor LMS. The Tutor LMS plugin must be installed and activated in order to exploit the vulnerability.

Cross-Site Request Forgery (CSRF) vulnerability in ThimPress RealPress realpress allows Cross Site Request Forgery.This issue affects RealPress: from n/a through <= 1.1.0.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in ThimPress LearnPress – Course Review learnpress-course-review allows Stored XSS.This issue affects LearnPress – Course Review: from n/a through <= 4.1.9.

The LearnPress – WordPress LMS Plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 4.3.2.4 via the get_item_permissions_check function. This makes it possible for unauthenticated attackers to extract sensitive data including user first names and last names. Other information such as social profile links and enrollment are also included.

The Gutenberg Thim Blocks – Page Builder, Gutenberg Blocks for the Block Editor plugin for WordPress is vulnerable to arbitrary file reads in all versions up to, and including, 1.0.1. This is due to insufficient path validation in the server-side rendering of the thim-blocks/icon block. This makes it possible for authenticated attackers, with Contributor-level access and above, to read the contents of arbitrary files on the server via the 'iconSVG' parameter, which can contain sensitive information such as wp-config.php.

The WP Hotel Booking plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.2.7. This is due to the plugin exposing the 'hotel_booking_fetch_customer_info' AJAX action to unauthenticated users without proper capability checks, relying only on a nonce for protection. This makes it possible for unauthenticated attackers to retrieve sensitive customer information including full names, addresses, phone numbers, and email addresses by providing a valid email address and a publicly accessible nonce.

The LearnPress – WordPress LMS Plugin for WordPress is vulnerable to unauthorized file deletion in versions up to, and including, 4.3.2.2 via the /wp-json/lp/v1/material/{file_id} REST API endpoint. This is due to a parameter mismatch between the DELETE operation and authorization check, where the endpoint uses file_id from the URL path but the permission callback validates item_id from the request body. This makes it possible for authenticated attackers, with teacher-level access, to delete arbitrary lesson material files uploaded by other teachers via sending a DELETE request with their own item_id (to pass authorization) while targeting another teacher's file_id.

The LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the catch_lp_ajax function in all versions up to, and including, 4.3.2. This makes it possible for unauthenticated attackers to modify course contents by adding/removing/updating/re-ordering sections or modifying section items.
