The Booking Package plugin for WordPress is vulnerable to Price Manipulation in versions up to, and including, 1.7.06 This is due to the intentForStripe() function passing user-controlled $_POST['amount'] directly to the Stripe PaymentIntent API without validation, and the commitStripe() function ignoring the server-calculated amount when confirming the payment. While the server correctly calculates the booking cost via getAmount() based on services, guests, taxes, and coupons, this calculated amount is never validated against or used to update the PaymentIntent because the critical code in CreditCard.php that would include the calculated amount in the PaymentIntent update is commented out. This makes it possible for unauthenticated attackers to book services at arbitrary prices (e.g., $0.01 instead of $500.00) by manipulating the amount parameter during PaymentIntent creation and completing the booking with the fraudulent payment.
Update to version 1.7.07, or a newer patched version
The Woostify plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.5.0 This is due to insufficient input sanitization and output escaping in the bundled Lity.js lightbox library, where user-controlled input from the href attribute is concatenated directly into a jQuery HTML string without sanitization. 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.
Update to version 2.5.1, or a newer patched version
The Timeline Blocks for Gutenberg plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'titleTag' attribute of the timeline-blocks/tb-timeline-blocks block in all versions up to, and including, 1.1.10 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
Update to version 1.1.11, or a newer patched version
The Social Post Embed plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Threads embed handler in all versions up to, and including, 2.0.1. This is due to insufficient input sanitization and output escaping on the user-supplied URL. 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.
Update to version 2.0.2, or a newer patched version
The WPC Smart Messages for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'text' attribute of the `wpcsm_text_rotator` shortcode in all versions up to, and including, 4.2.8. This is due to insufficient input sanitization and output escaping on user supplied attributes. 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.
Update to version 4.2.9, or a newer patched version
The LatePoint – Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Privilege Escalation in versions up to and including 5.4.1. This is due to a missing authorization check in the execute() method of the connect-customer-to-wp-user ability, which only requires the customer__edit capability granted to the latepoint_agent role by default, without verifying whether the target WordPress user ID belongs to a privileged account. This makes it possible for authenticated attackers with the latepoint_agent role to link any LatePoint customer record to an administrator's WordPress account and subsequently reset the administrator's password via the normal customer password-reset flow, resulting in full site takeover.
Update to version 5.4.2, or a newer patched version
The Highland Software Custom Role Manager plugin for WordPress is vulnerable to Privilege Escalation in versions up to and including 1.0.0. This is due to insufficient authorization checks in the hscrm_save_user_roles() function, which is hooked to the personal_options_update action accessible by any authenticated user. This makes it possible for authenticated attackers, with Subscriber-level access or higher, to potentially modify user roles via the profile update form.
Update to version 1.0.1, or a newer patched version
The ITERAS plugin for WordPress is vulnerable to Stored Cross-Site Scripting via multiple shortcodes (iteras-ordering, iteras-signup, iteras-paywall-login, iteras-selfservice) in all versions up to and including 1.8.2. This is due to insufficient input sanitization and output escaping in the combine_attributes() function. The function directly concatenates shortcode attribute values into JavaScript code within tags using double-quoted string interpolation (line 489: '"'.$key.'": "'.$value.'"') without any escaping. An attacker can break out of the JavaScript string context by including a double-quote character in a shortcode attribute value and inject arbitrary JavaScript. 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.
Update to version 1.8.3, or a newer patched version
The HubSpot All-In-One Marketing - Forms, Popups, Live Chat plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 11.3.32 via the leadin/public/admin/class-adminconstants.php file. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract a list of all installed plugins and their versions which can be leveraged for reconnaissance and further attacks.
Update to version 11.3.33, or a newer patched version
The Liaison Site Prober plugin for WordPress is vulnerable to Information Exposure in all versions up to and including 1.2.1 via the /wp-json/site-prober/v1/logs REST API endpoint. The permissions_read() permission callback unconditionally returns true (via __return_true()) instead of checking for appropriate capabilities. This makes it possible for unauthenticated attackers to retrieve sensitive audit log data including IP addresses, user IDs, usernames, login/logout events, failed login attempts, and detailed activity descriptions.
Update to version 1.2.2, or a newer patched version
