Title
OpenEMR's Portal Payment Endpoint Trusts User-Controlled pid
Summary
OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, in `portal/portal_payment.php`, the patient id used for the page is taken from the request (`$pid = $_REQUEST['pid'] ?? $pid` and `$pid = ($_REQUEST['hidden_patient_code'] ?? null) > 0 ? $_REQUEST['hidden_patient_code'] : $pid`) instead of being fixed to the authenticated portal user. The portal session already has a valid `$pid` for the logged-in patient. Overwriting it with user-supplied values and using it without authorization allows a portal user to view and interact with another patient's demographics, invoices, and payment history—horizontal privilege escalation and IDOR. Version 8.0.0 contains a fix for the issue.

Title
Gogs Allows Cross-Repository Comment Deletion via DeleteComment
Summary
Gogs is an open source self-hosted Git service. In versions 0.13.4 and below, the DeleteComment API does not verify that the comment belongs to the repository specified in the URL. This allows a repository administrator to delete comments from any other repository by supplying arbitrary comment IDs, bypassing authorization controls. The DeleteComment function retrieves a comment by ID without verifying repository ownership and the Database function DeleteCommentByID performs no repository validation. This issue has been fixed in version 0.14.0.

Title
Outline's IDOR allows unauthorized viewing and seizing of private deleted drafts
Summary
Outline is a service that allows for collaborative documentation. Prior to 1.4.0, an Insecure Direct Object Reference (IDOR) vulnerability in the document restoration logic allows any team member to unauthorizedly restore, view, and seize ownership of deleted drafts belonging to other users, including administrators. By bypassing ownership validation during the restore process, an attacker can access sensitive private information and effectively lock the original owner out of their own content. Version 1.4.0 fixes the issue.

Title
MarkUs has a submission-view IDOR exposes all student submissions
Summary
MarkUs is a web application for the submission and grading of student assignments. Prior to 2.9.1, the courses/<:course_id>/assignments/<:assignment_id>/submissions/html_content accepted a select_file_id parameter to serve SubmissionFile objects containing a record of files submitted by students. This parameter was not correctly scoped to the requesting user, allowing users access arbitrary submission file contents by id. This vulnerability is fixed in 2.9.1.

Title
OpenProject has an IDOR on MeetingAgendaItems allows cross-project meeting agenda item transfer
Summary
OpenProject is an open-source, web-based project management software. Prior to 17.0.2, the drag&drop handler moving an agenda item to a different section was not properly checking if the target meeting section is part of the same meeting (or is the backlog, in case of recurring meetings). This allowed an attacker to move a meeting agenda item into a different meeting. The attacker did not get access to meetings, but they could add arbitrary agenda items, that could cause confusions. The vulnerability is fixed in 17.0.2.

Title
Open eClass Unauthenticated IDOR Allows Access to Arbitrary User Files
Summary
The Open eClass platform (formerly known as GUnet eClass) is a complete course management system. Prior to version 4.2, an Insecure Direct Object Reference (IDOR) vulnerability allows unauthenticated remote attackers to access personal files of other users by directly requesting predictable user identifiers. This issue has been patched in version 4.2.

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.
