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.

Insecure Direct Object Reference (IDOR) in Bagisto v.1.5.1 allows an attacker to obtain sensitive information via the invoice ID parameter.

Spree is an open source e-commerce solution built with Ruby on Rails. Prior to versions 4.10.2, 5.0.7, 5.1.9, and 5.2.5, an Authenticated Insecure Direct Object Reference (IDOR) vulnerability was identified that allows an authenticated user to retrieve other users’ address information by modifying an existing order. By editing an order they legitimately own and manipulating address identifiers in the request, the backend server accepts and processes references to addresses belonging to other users, subsequently associating those addresses with the attacker’s order and returning them in the response. This issue has been patched in versions 4.10.2, 5.0.7, 5.1.9, and 5.2.5.

Improper Access Control (IDOR) in the Graylog API, version 2.2.3, which occurs when modifying the user ID in the URL. An authenticated user can access other user's profiles without proper authorization checks. Exploiting this vulnerability allows valid users of the system to be listed and sensitive third-party information to be accessed, such as names, email addresses, internal identifiers, and last activity. The endpoint 'http://<IP>:12900/users/<my_user>' does not implement object-level authorization validations.

Attackers can successfully request arbitrary snippet IDs, including E-Mail signatures of other users within the same context. Signatures of other users could be read even though they are not explicitly shared. We improved permission handling when requesting snippets that are not explicitly shared with other users. No publicly available exploits are known.

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, the Message Center accepts the URL parameter `show_all=yes` and passes it to `getPnotesByUser()`, which returns all internal messages (all users’ notes). The backend does not verify that the requesting user is an administrator before honoring `show_all=yes`. The "Show All" link is also visible to non-admin users. As a result, any authenticated user can view the entire internal message list by requesting `messages.php?show_all=yes`. Version 8.0.0 patches the issue.

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, the document controller’s `patient_picture` context serves the patient’s photo by document ID or patient ID without verifying that the current user is authorized to access that patient. An authenticated user with document ACL can supply another patient’s ID and retrieve their photo. Version 8.0.0 fixes the issue.

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to version 8.0.0, the Layout-Based Form (LBF) printable view accepts `formid` and `visitid` (or `patientid`) from the request and does not verify that the form belongs to the current user’s authorized patient/encounter. An authenticated user with LBF access can enumerate form IDs and view or print any patient’s encounter forms. Version 8.0.0 fixes the issue.

OpenEMR is a free and open source electronic health records and medical practice management application. In versions up to and including 8.0.0, the eye exam (eye_mag) view loads data by `form_id` (or equivalent) without verifying that the form belongs to the current user’s patient/encounter context. An authenticated user can access or edit any patient’s eye exam by supplying another form ID; in some flows the session’s active patient may also be switched. A fix is available on the `main` branch of the OpenEMR GitHub repository.

Prior to version 2026.2.0, the `userCollection` GraphQL query accepts an arbitrary collection ID and returns the full collection data — including title, type, and the serialized `data` field containing HTTP requests with headers and potentially secrets — to any authenticated user, without verifying that the requesting user owns the collection. This is an Insecure Direct Object Reference (IDOR) caused by a missing authorization check that exists on every other operation in the same resolver. Version 2026.2.0 fixes the issue.

Axios Cache Interceptor is a cache interceptor for axios. Prior to version 1.11.1, when a server calls an upstream service using different auth tokens, axios-cache-interceptor returns incorrect cached responses, leading to authorization bypass. The cache key is generated only from the URL, ignoring request headers like `Authorization`. When the server responds with `Vary: Authorization` (indicating the response varies by auth token), the library ignores this, causing all requests to share the same cache regardless of authorization. Server-side applications (APIs, proxies, backend services) that use axios-cache-interceptor to cache requests to upstream services, handle requests from multiple users with different auth tokens, and upstream services replies on `Vary` to differentiate caches are affected. Browser/client-side applications (single user per browser session) are not affected. Services using different auth tokens to call upstream services will return incorrect cached data, bypassing authorization checks and leaking user data across different authenticated sessions. After `v1.11.1`, automatic `Vary` header support is now enabled by default. When server responds with `Vary: Authorization`, cache keys now include the authorization header value. Each user gets their own cache.

Bhima version 1.27.0 allows an attacker authenticated with normal user permissions to view sensitive data of other application users and data that should only be viewed by the administrator. This is possible because the application is vulnerable to IDOR, it does not properly validate user permissions with respect to certain actions the user can perform.

A vulnerability in infiniflow/ragflow version RAGFlow-0.13.0 allows for partial account takeover via insecure data querying. The issue arises from the way tenant IDs are handled in the application. If a user has access to multiple tenants, they can manipulate their tenant access to query and access API tokens of other tenants. This vulnerability affects the following endpoints: /v1/system/token_list, /v1/system/new_token, /v1/api/token_list, /v1/api/new_token, and /v1/api/rm. An attacker can exploit this to access other tenants' API tokens, perform actions on behalf of other tenants, and access their data.
