Title
Foreman: foreman: information disclosure via improper validation of nested request parameters
Summary
A flaw was found in Foreman. An authenticated user with host-edit permissions could exploit a cross-tenant information disclosure vulnerability. This flaw occurs because the taxonomy_scope controller method does not properly validate organization and location IDs from nested request parameters, bypassing existing authorization checks. This allows the user to leak sensitive infrastructure metadata, including subnet topology, IP ranges, gateways, DNS servers, and VLAN IDs, from organizations and locations they are not authorized to access.

Title
Foreman: foreman: unauthorized modification of host configurations via broken access control
Summary
A flaw was found in Foreman. This broken access control vulnerability allows an authenticated user with host-edit permissions to retarget an existing lookup value override to a different host. This is achieved by modifying the match field through nested host attributes, effectively bypassing authorisation checks. The consequence is the potential for unauthorised modification of managed host configurations across different organisational and location boundaries.

Title
WCFM - WooCommerce Frontend Manager <= 6.7.25 - Insecure Direct Object References to Autenticated (Vendor+) Arbitrary Post/Product Manipulation
Summary
The WCFM – Frontend Manager for WooCommerce along with Bookings Subscription Listings Compatible plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 6.7.25 via multiple AJAX actions including `wcfm_modify_order_status`, `delete_wcfm_article`, `delete_wcfm_product`, and the article management controller due to missing validation on user-supplied object IDs. This makes it possible for authenticated attackers, with Vendor-level access and above, to modify the status of any order, delete or modify any post/product/page, regardless of ownership.

Title
Awesome Support <= 6.3.7 - Authenticated (Subscriber+) Insecure Direct Object Reference to Unauthorized Ticket Reply Access via 'ticket_id' Parameter
Summary
The Awesome Support – WordPress HelpDesk & Support Plugin plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 6.3.7. This is due to the wpas_get_ticket_replies_ajax() function failing to verify whether the authenticated user has permission to view the specific ticket being requested. This makes it possible for authenticated attackers, with subscriber-level access and above, to access sensitive information from all support tickets in the system by manipulating the ticket_id parameter.

Title
Keycloak: keycloak: unauthorized resource access and data modification via insecure direct object reference
Summary
A flaw was found in Keycloak. An authenticated client could exploit an Insecure Direct Object Reference (IDOR) vulnerability in the Authorization Services Protection API endpoint. By knowing or obtaining a resource's unique identifier (UUID) belonging to another Resource Server within the same realm, the client could bypass authorization checks. This allows the client to perform unauthorized GET, PUT, and DELETE operations on resources, leading to information disclosure and potential unauthorized modification or deletion of data.

Mitigation
Architecture and Design
For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
Mitigation
Architecture and Design
Implementation
Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
Mitigation
Architecture and Design
Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
