BuddyPress 14.4.0 contains an insecure direct object reference vulnerability in the messages REST API that allows authenticated attackers to access arbitrary private message threads by supplying a user_id parameter in the request. Attackers can pass another user's identifier to the get_item_permissions_check method, which validates the supplied user_id instead of the logged-in user and is reused by the update and delete handlers, to read, reply to, or delete any user's private messages.

——6The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.0.8 via the 'student_id' parameter due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with subscriber-level access and above, to disclose the email address and Tutor profile phone number of arbitrary WordPress users, including Administrators, by iterating over user IDs via the student_id parameter.11hCVE-2026-769015.8 MED26.6%
——8CordysCRM is an open source AI-powered customer relationship management system that supports private deployment. Prior to 1.7.4, GET /pool/lead/get/{id} in PoolClueController.get and GET /pool/account/get/{id} in PoolCustomerController.get use bare pool-read permission checks without the CsPermission resourceId binding that enforces per-record data scope. An authenticated user with the ordinary CLUE_MANAGEMENT_POOL:READ or CUSTOMER_MANAGEMENT_POOL:READ permission can supply another record's id and cause unscoped primary-key getters to return leads or accounts owned by other users, departments, or organizations. Exposed data includes contact names, phone numbers, owner and department attribution, and custom field values. This issue is fixed in version 1.7.4.1d
