Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.2, the `LinkSharing.ReadAll()` method allows link share authenticated users to list all link shares for a project, including their secret hashes. While `LinkSharing.CanRead()` correctly blocks link share users from reading individual shares via `ReadOne`, the `ReadAllWeb` handler bypasses this check by never calling `CanRead()`. An attacker with a read-only link share can retrieve hashes for write or admin link shares on the same project and authenticate with them, escalating to full admin access. Version 2.2.2 patches the issue.

Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.1, when the Vikunja API returns tasks, it populates the `related_tasks` field with full task objects for all related tasks without checking whether the requesting user has read permission on those tasks' projects. An authenticated user who can read a task that has cross-project relations will receive full details (title, description, due dates, priority, percent completion, project ID, etc.) of tasks in projects they have no access to. Version 2.2.1 patches the issue.

Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.1, the `GET /api/v1/projects/:project/webhooks` endpoint returns webhook BasicAuth credentials (`basic_auth_user` and `basic_auth_password`) in plaintext to any user with read access to the project. While the existing code correctly masks the HMAC `secret` field, the BasicAuth fields added in a later migration were not given the same treatment. This allows read-only collaborators to steal credentials intended for authenticating against external webhook receivers. Version 2.2.1 patches the issue.

Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.0, an authenticated user can read any task comment by ID, regardless of whether they have access to the task the comment belongs to, by substituting the task ID in the API URL with a task they do have access to. Version 2.2.0 fixes the issue.

Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.1, the `DELETE /api/v1/projects/:project/shares/:share` endpoint does not verify that the link share belongs to the project specified in the URL. An attacker with admin access to any project can delete link shares from other projects by providing their own project ID combined with the target share ID. Version 2.2.1 patches the issue.

Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.1, `TaskAttachment.ReadOne()` queries attachments by ID only (`WHERE id = ?`), ignoring the task ID from the URL path. The permission check in `CanRead()` validates access to the task specified in the URL, but `ReadOne()` loads a different attachment that may belong to a task in another project. This allows any authenticated user to download or delete any attachment in the system by providing their own accessible task ID with a target attachment ID. Attachment IDs are sequential integers, making enumeration trivial. Version 2.2.1 patches the issue.

OpenEMR 6.0.0 has a pnotes_print.php?noteid= Insecure Direct Object Reference vulnerability via which an attacker can read the messages of all users.

Nextcloud Circles is an open source social network built for the nextcloud ecosystem. In affected versions the Nextcloud Circles application allowed any user to join any "Secret Circle" without approval by the Circle owner leaking private information. It is recommended that Nextcloud Circles is upgraded to 0.19.15, 0.20.11 or 0.21.4. There are no workarounds for this issue.

A flaw in the binding process of Govee’s cloud platform and devices allows a remote attacker to bind an existing, online Govee device to the attacker’s account, resulting in full control of the device and removal of the device from its legitimate owner’s account. The server‑side API allows device association using a set of identifiers: "device", "sku", "type", and a client‑computed "value", that are not cryptographically bound to a secret originating from the device itself. The vulnerability has been verified for the Govee H6056 - lamp device in firmware version 1.08.13, but may affect also other Govee cloud‑connected devices. The vendor is investigating other potentially affected models. The vendor has deployed server-side security enhancements and automatic firmware updates for model H6056. Most of H6056 devices have been successfully patched through automatic updates. Remaining H6056 users with upgradeable hardware versions must manually update firmware through the Govee Home app while keeping their device WiFi-connected. Users should open the Govee Home app, tap their H6056 device card to enter the device details page, tap the settings icon in the upper right corner, navigate to Device Information section (Firmware Version), and tap the Update button to install the security patch immediately. Govee H6056 devices with hardware versions 1.00.10 or 1.00.11 cannot receive firmware update due to hardware limitations.

The User Meta – User Profile Builder and User management plugin plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.1.1 via the getUser() due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Contributor-level access and above, to obtain user meta values from form fields. Please note that this requires a site administrator to create a form that displays potentially sensitive information like password hashes. This may also be exploited by unauthenticated users if the 'user-meta-public-profile' shortcode is used insecurely.

The User Private Files – WordPress File Sharing Plugin plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.1.0 via the 'dpk_upvf_update_doc' due to missing validation on the 'docid' user controlled key. This makes it possible for authenticated attackers, with subscriber-level access and above, to gain access to other user's private files.

Insecure direct object reference (IDOR) vulnerability in ICREM H8 SSRMS allows attackers to disclose sensitive information via the Print Invoice Functionality.

This vulnerability exists in TechExcel Back Office Software versions prior to 1.0.0 due to improper access controls on certain API endpoints. An authenticated remote attacker could exploit this vulnerability by manipulating a parameter through API request URL which could lead to unauthorized access to sensitive information belonging to other users.

The Ocean Extra WordPress plugin before 2.1.3 does not ensure that the template to be loaded via a shortcode is actually a template, allowing any authenticated users such as subscriber to retrieve the content of arbitrary posts, such as draft, private or even password protected ones.

Chat2DB before 5.3.0 contains an insecure direct object reference vulnerability in the GET /api/connection/datasource/{id} endpoint. The handler calls dataSourceService.queryExistent(id, ...) without an ownership check and returns the decrypted password field, allowing any authenticated non-admin user to enumerate datasource IDs and read the plaintext database credentials of datasources owned by other users.

TheHive through 4.1.24 contains a broken object-level authorization vulnerability in the attachment download endpoints that allows any authenticated user to access attachments belonging to other organizations by supplying a content-hash identifier. Attackers can exploit the missing organization-scoped authorization check in AttachmentSrv.visible, which is implemented as a pass-through traversal, to download arbitrary attachments.

Authorization Bypass Through User-Controlled Key vulnerability in Beefull Energy Technologies Beefull App allows Exploitation of Trusted Identifiers. This issue affects Beefull App: before 24.07.2025.

Biscom Secure File Transfer (SFT) 5.0.1050 through 5.1.1067 and 6.0.1000 through 6.0.1003 allows Insecure Direct Object Reference (IDOR) by an authenticated sender because of an error in a file-upload feature. This is fixed in 5.1.1068 and 6.0.1004.

GLPI is an open-source asset and IT management software package that provides ITIL Service Desk features, licenses tracking and software auditing. In GLPI before version 9.5.4 there is an Insecure Direct Object Reference (IDOR) on "Solutions". This vulnerability gives an unauthorized user the ability to enumerate GLPI items names (including users logins) using the knowbase search form (requires authentication). To Reproduce: Perform a valid authentication at your GLPI instance, Browse the ticket list and select any open ticket, click on Solution form, then Search a solution form that will redirect you to the endpoint /"glpi/front/knowbaseitem.php?item_itemtype=Ticket&item_items_id=18&forcetab=Knowbase$1", and the item_itemtype=Ticket parameter present in the previous URL will point to the PHP alias of glpi_tickets table, so just replace it with "Users" to point to glpi_users table instead; in the same way, item_items_id=18 will point to the related column id, so changing it too you should be able to enumerate all the content which has an alias. Since such id(s) are obviously incremental, a malicious party could exploit the vulnerability simply by guessing-based attempts.

Indico is an event management system that uses Flask-Multipass, a multi-backend authentication system for Flask. Starting in version 2.2 and prior to version 3.3.7, an endpoint used to display details of users listed in certain fields (such as ACLs) could be misused to dump basic user details (such as name, affiliation and email) in bulk. Version 3.3.7 fixes the issue. Owners of instances that allow everyone to create a user account, who wish to truly restrict access to these user details, should consider restricting user search to managers. As a workaround, it is possible to restrict access to the affected endpoints (e.g. in the webserver config), but doing so would break certain form fields which could no longer show the details of the users listed in those fields, so upgrading instead is highly recommended.

ArcadeDB versions before 26.7.2 contain an authorization bypass vulnerability in HTTP handlers for time series, batch, Prometheus, and Grafana endpoints that fail to validate database access permissions. Attackers can access and modify databases they are not authorized to use by directly calling affected endpoints with arbitrary database parameters.

The OKLOK (3.1.1) mobile companion app for Fingerprint Bluetooth Padlock FB50 (2.3) allows remote attackers to submit API requests using authenticated but unauthorized tokens, resulting in IDOR issues. A remote attacker can use their own token to make unauthorized API requests on behalf of arbitrary user IDs. Valid and current user IDs are trivial to guess because of the user ID assignment convention used by the app. A remote attacker could harvest email addresses, unsalted MD5 password hashes, owner-assigned lock names, and owner-assigned fingerprint names for any range of arbitrary user IDs.

Service Center developed by BankPro E-Service Technology has an Insecure Direct Object Reference vulnerability, allowing authenticated remote attackers to modify the parameter of a specific query function to access other users' EC order details.

Canon Medical Informatics Vitrea Vision 7.7.76.1 does not adequately enforce access controls. An authenticated user is able to gain unauthorized access to imaging records by tampering with the vitrea-view/studies/search patientId parameter.

The 'Medical History' module in PHPGurukul Hospital Management System v4.0 contains an Insecure Direct Object Reference (IDOR) vulnerability. The application fails to verify that the requested 'viewid' parameter belongs to the currently authenticated patient. This allows a user to access the confidential medical records of other patients by iterating the 'viewid' integer.

Insecure Direct Object Reference (IDOR) vulnerability in Deepfiction AI (deepfiction.ai) thru June 3, 2025, allowing attackers to chat with the LLM using other users' credits via sensitive information gained by the /browse/stories endpoint.

The Awesome Support WordPress plugin before 6.1.2 does not ensure that the exported tickets archive to be downloaded belongs to the user making the request, allowing a low privileged user, such as subscriber to download arbitrary exported tickets via an IDOR vector

CVAT is an open source interactive video and image annotation tool for computer vision. Versions 2.2.0 through 2.39.0 have no validation during the import process of a project or task backup to check that the filename specified in the query parameter refers to a TUS-uploaded file belonging to the same user. As a result, if an attacker with a CVAT account and a `user` role knows the filenames of other users' uploads, they could potentially access and steal data by creating projects or tasks using those files. This issue does not affect annotation or dataset TUS uploads, since in this case object-specific temporary directories are used. Users should upgrade to CVAT 2.40.0 or a later version to receive a patch. No known workarounds are available.

Leantime 3.6.2 and prior contains a broken access control vulnerability that allows authenticated users to read milestone data from projects they are not assigned to by supplying arbitrary integer milestone IDs to the tickets.getMilestone JSON-RPC endpoint. Attackers can enumerate integer milestone IDs through the JSON-RPC API to access project planning information, milestone titles, descriptions, and timelines across all projects on the instance regardless of project membership.

Red Hat CloudForms 4.7 and 5 leads to insecure direct object references (IDOR) and functional level access control bypass due to missing privilege check. Therefore, if an attacker knows the right criteria, it is possible to access some sensitive data within the CloudForms.

In Rundeck before version 3.2.6, authenticated users can craft a request that reveals Execution data and logs and Job details that they are not authorized to see. Depending on the configuration and the way that Rundeck is used, this could result in anything between a high severity risk, or a very low risk. If access is tightly restricted and all users on the system have access to all projects, this is not really much of an issue. If access is wider and allows login for users that do not have access to any projects, or project access is restricted, there is a larger issue. If access is meant to be restricted and secrets, sensitive data, or intellectual property are exposed in Rundeck execution output and job data, the risk becomes much higher. This vulnerability is patched in version 3.2.6

https://www.sourcecodester.com/ Online Enrollment Management System in PHP and PayPal Free Source Code 1.0 is affected by: Incorrect Access Control. The impact is: gain privileges (remote).

XXL-Job version 2.4.2 contains an insecure direct object reference vulnerability that allows authenticated users to read execution log content from job groups they are not authorized to access by supplying arbitrary sequential log IDs to the logDetailCat endpoint. Attackers can enumerate log records across all job groups by calling the logDetailCat endpoint with incremented logId parameter values, bypassing the permission check present in the sibling logDetailPage endpoint, and retrieve sensitive log content from restricted job groups.

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.
