| CVE-2024-13063 | Med | 0.44 | 6.8 | 0.00 | Sep 3, 2025 | Authorization Bypass Through User-Controlled Key vulnerability in Akinsoft MyRezzta allows Forceful Browsing.This issue affects MyRezzta: from s2.02.02 before v2.05.01. | |
| CVE-2021-37577 | Med | 0.44 | 6.8 | 0.00 | Oct 1, 2024 | Bluetooth LE and BR/EDR Secure Connections pairing and Secure Simple Pairing using the Passkey entry protocol in Bluetooth Core Specifications 2.1 through 5.3 may permit an unauthenticated man-in-the-middle attacker to identify the Passkey used during pairing by reflection of a crafted public key with the same X coordinate as the offered public key and by reflection of the authentication evidence of the initiating device, potentially permitting this attacker to complete authenticated pairing with the responding device using the correct Passkey for the pairing session. This is a related issue to CVE-2020-26558. | |
| CVE-2026-41649 | Hig | 0.43 | 7.7 | 0.00 | Apr 28, 2026 | Outline is a service that allows for collaborative documentation. The `shares.create` API endpoint starting in version 0.86.0 and prior to version 1.7.0 has an insecure direct object reference.. When both `collectionId` and `documentId` are provided in the request, the authorization logic only checks access to the collection, completely ignoring the document. This allows an authenticated attacker to generate a valid public share link for any document on the platform, including documents belonging to other workspaces. The full document contents can then be retrieved via the `documents.info` endpoint. Version 1.7.0 contains a patch. | |
| CVE-2024-9617 | Med | 0.43 | 6.5 | 0.16 | Mar 20, 2025 | An IDOR vulnerability in danswer-ai/danswer v0.3.94 allows an attacker to view any files. The application does not verify whether the attacker is the creator of the file, allowing the attacker to directly call the GET /api/chat/file/{file_id} interface to view any user's file. | |
| CVE-2023-2548 | Med | 0.43 | 6.6 | 0.00 | May 16, 2023 | The RegistrationMagic plugin for WordPress is vulnerable to Insecure Direct Object References in versions up to, and including, 5.2.0.5. This is due to the plugin providing user-controlled access to objects, letting a user bypass authorization and access system resources. This makes it possible for authenticated attackers, with administrator-level permissions and above, to change user passwords and potentially take over super-administrator accounts in multisite setup. | |
| CVE-2026-44426 | Med | 0.42 | 6.5 | 0.00 | May 13, 2026 | ShellHub is a centralized SSH gateway. Prior to 0.24.2, GET /api/namespaces/:tenant returns the full namespace object — including the members list (user IDs, e-mails, roles), settings, and device counts — to any caller authenticated by an API Key, for any tenant, regardless of the API Key's own tenant scope. The handler conditionally skips the membership check when the user ID (X-ID) is absent, which is exactly the case for API Key authentication. This vulnerability is fixed in 0.24.2. | |
| CVE-2026-44424 | Med | 0.42 | 6.5 | 0.00 | May 13, 2026 | ShellHub is a centralized SSH gateway. Prior to 0.24.2, GET /api/devices/:uid returns the full device object whenever the caller is authenticated, without verifying that the device belongs to the caller's namespace (tenant). Any authenticated user (JWT or API Key) who knows or can guess a device UID can read device metadata from any other namespace. This vulnerability is fixed in 0.24.2. | |
| CVE-2026-44423 | Med | 0.42 | 6.5 | 0.00 | May 13, 2026 | ShellHub is a centralized SSH gateway. Prior to 0.24.2, GET /api/sessions/:uid returns the full session object for any authenticated caller, without scoping by the caller's tenant. An authenticated user can read session records (SSH username, device UID, remote IP, terminal type, authenticated flag, timestamps) belonging to any other namespace. This vulnerability is fixed in 0.24.2. | |
| CVE-2026-42277 | Med | 0.42 | 6.5 | 0.00 | May 8, 2026 | Onyx is an open-source AI platform. Prior to versions 3.0.9, 3.1.6, and 3.2.6, the GET /chat/file/{file_id} endpoint allows any authenticated user to download any other user's uploaded files by providing the file UUID. The endpoint verifies the caller is authenticated but never checks that the file belongs to them. An attacker who knows or obtains a file UUID can access confidential documents, chat attachments, and other files uploaded by any user in the system. This issue has been patched in versions 3.0.9, 3.1.6, and 3.2.6. | |
| CVE-2026-41950 | Med | 0.42 | 6.5 | 0.00 | May 5, 2026 | Dify before version 1.14.0 contains an authorization bypass vulnerability that allows authenticated users to read the full contents of files uploaded by other users within the same tenant by supplying an arbitrary file UUID in the files array of a chat-messages request. Attackers can exploit insufficient permission verification in the chat-messages endpoints to access files without ownership validation, bypassing workspace separation and signed URL protections to retrieve sensitive file contents through workflow processing. | |
| CVE-2026-3454 | Med | 0.42 | 6.5 | 0.00 | May 5, 2026 | The GenerateBlocks plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.2.0. This is due to missing object-level authorization checks in the /wp-json/generateblocks/v1/dynamic-tag-replacements REST endpoint. The endpoint only verifies that the user has the edit_posts capability but does not verify the user has permission to access the specific post or its associated data referenced by attacker-controlled id parameters in dynamic tag content. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract sensitive information from arbitrary posts including author email addresses and non-protected post meta values by crafting dynamic tag payloads such as {{post_meta id:<target>|key:<meta_key>}} and {{post_title id:<target>|link:author_email}}. | |
| CVE-2026-42227 | Med | 0.42 | 6.5 | 0.00 | May 4, 2026 | n8n is an open source workflow automation platform. Prior to versions 1.123.32, 2.17.4, and 2.18.1, an authenticated user with a valid API key scoped to variable:list could read variables from projects they are not a member of by supplying an arbitrary projectId query parameter to the public API variables endpoint. The handler queried the variables repository directly without enforcing project membership checks, bypassing the authorization-aware service layer used by the internal enterprise controller. If variables were misused to store sensitive information such as credentials or tokens, they should be rotated immediately. This issue only affects licensed enterprise or team deployments with multiple projects and the variables feature enabled. This issue has been patched in versions 1.123.32, 2.17.4, and 2.18.1. | |
| CVE-2026-5337 | Med | 0.42 | 6.5 | 0.00 | May 3, 2026 | During the analysis, it was identified that authenticated attackers with Subscriber-level access or higher are able to perform an Insecure Direct Object Reference (IDOR) attack. This vulnerability exists because the Frontend File Manager Plugin WordPress plugin through 23.6 does not properly validate user authorization for the requested uploaded file when processing download requests. By modifying the value of the 'file_id' parameter in the download endpoint (e.g., http://localhost/?do=wpfm_download&file_id=40&nm_file_nonce=a36fb893f1), an attacker can access files belonging to other users, including privileged users such as administrators. This allows unauthorized access/read to sensitive data stored within the application. | |
| CVE-2026-7681 | Med | 0.42 | 6.5 | 0.00 | May 3, 2026 | A security vulnerability has been detected in jsbroks COCO Annotator up to 0.11.1. Affected by this vulnerability is an unknown functionality of the file backend/webserver/api/datasets.py of the component Dataset API. The manipulation of the argument DatasetId leads to authorization bypass. The attack may be initiated remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way. | |
| CVE-2026-6542 | Med | 0.42 | 6.5 | 0.00 | Apr 30, 2026 | IBM Langflow OSS 1.0.0 through 1.8.4 could allow any user to supply a flow_id to read transaction logs and vertex build data belonging to other users, and to delete persisted vertex build data for another user's flow. | |
| CVE-2026-6355 | Med | 0.42 | 6.5 | 0.00 | Apr 22, 2026 | A vulnerability in the web application allows unauthorized users to access and manipulate sensitive data across different tenants by exploiting insecure direct object references. This could lead to unauthorized access to sensitive information and unauthorized changes to the tenant's configuration. | |
| CVE-2026-41127 | Med | 0.42 | 6.5 | 0.00 | Apr 22, 2026 | BigBlueButton is an open-source virtual classroom. Versions prior to 3.0.24 have a missing authorization that allows viewers to inject/overwrite captions Version 3.0.24 tightened the permissions on who is able to submit captions. No known workarounds are available. | |
| CVE-2026-40907 | Med | 0.42 | 6.5 | 0.00 | Apr 21, 2026 | WWBN AVideo is an open source video platform. In versions 29.0 and prior, the endpoint `plugin/Live/view/Live_restreams/list.json.php` contains an Insecure Direct Object Reference (IDOR) vulnerability that allows any authenticated user with streaming permission to retrieve other users' live restream configurations, including third-party platform stream keys and OAuth tokens (access_token, refresh_token) for services like YouTube Live, Facebook Live, and Twitch. Commit d5992fff2811df4adad1d9fc7d0a5837b882aed7 fixes the issue. | |
| CVE-2025-66954 | Med | 0.42 | 6.5 | 0.00 | Apr 20, 2026 | A vulnerability exists in the Buffalo Link Station version 1.85-0.01 that allows unauthenticated or guest-level users to enumerate valid usernames and their associated privilege roles. The issue is triggered by modifying a parameter within requests sent to the /nasapi endpoint. | |
| CVE-2026-34370 | Med | 0.42 | 6.5 | 0.00 | Apr 14, 2026 | Chamilo LMS is an open-source learning management system. In versions prior to 2.0.0-RC.3, the notebook module contains an Insecure Direct Object Reference (IDOR) vulnerability that allows any authenticated student to read the private course notes of any other user on the platform by manipulating the notebook_id parameter in the editnote action. The application fetches the note content using only the supplied integer ID without verifying that the requesting user owns the note, and the full title and HTML body are rendered in the edit form and returned to the attacker's browser. While ownership checks exist in the write paths (updateNote() and delete_note()), they are entirely absent from the read path (get_note_information()). This issue has been fixed in version 2.0.0-RC.3. |
