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.
LearnPress WordPress LMS Plugin versions up to and including 4.3.6 contains a missing authorization vulnerability. This flaw allows unauthenticated attackers to access sensitive information such as plaintext passwords and content of unpublished courses by manipulating specific API parameters. The vulnerability is due to insufficient access control on the /wp-json/lp/v1/courses/archive-course endpoint.
The LearnPress – Backup & Migration Tool WordPress plugin up to version 4.1.4 is vulnerable to PHP Object Injection via deserialization of untrusted input. This vulnerability requires an attacker to have administrator-level privileges. Exploitation depends on the presence of a gadget chain (POP chain) in other installed plugins or themes. Without such a chain, the vulnerability has no impact. If a POP chain exists, it could allow actions such as arbitrary file deletion, sensitive data retrieval, or code execution.
The LearnPress – Backup & Migration Tool WordPress plugin contains a path traversal vulnerability in versions up to and including 4.1.4. This flaw allows authenticated users with administrator-level privileges or higher to read arbitrary files on the server by exploiting the 'import-user-file' parameter. The vulnerability can expose sensitive information stored on the server. The CVSS score is 4.9, indicating a medium severity risk. No official patch or remediation guidance has been provided yet.
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.
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in ThimPress LearnPress allows Reflected XSS.
This issue affects LearnPress: from n/a through 4.3.6.
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 WordPress plugin up to version 4.3.2.8 contains a critical vulnerability (CVE-2026-4365) due to missing authorization checks in the delete_question_answer() function. An unauthenticated attacker can exploit a publicly exposed wp_rest nonce in frontend HTML to send crafted POST requests to delete any quiz answer option without proper capability or ownership verification. This results in unauthorized data deletion with high impact on integrity and availability.
LearnPress – WordPress LMS Plugin versions up to 4.3.3 contain a stored cross-site scripting (XSS) vulnerability in the 'skin' attribute of the learn_press_courses shortcode. This occurs due to insufficient sanitization and escaping of the attribute value, which is directly used in HTML generation without proper escaping. Authenticated users with Contributor-level access or higher can exploit this to inject malicious scripts that execute when other users view the affected pages. The vulnerability has a CVSS score of 6.4, indicating medium severity.
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.
