No known workarounds are available.

PhotoPrism before 260601-a7d098548 contains a broken access control vulnerability that allows authenticated non-admin users to modify other users' profile information by sending requests to arbitrary user endpoints. Attackers can exploit the missing session-to-user identifier validation in the PUT users API endpoint to overwrite another user's profile details without authorization.

The Replace Image plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.1.10 via the image replacement functionality due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Author-level access and above, to replace images uploaded by higher level users such as admins.

The contains an IDOR vulnerability that allows a user to comment on a private post by manipulating the ID included in the request

The DW Question & Answer Pro WordPress plugin through 1.3.4 does not check that the comment to edit belongs to the user making the request, allowing any user to edit other comments.

Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.6, POST /api/v1/calendars/events/{event_id}/update validates that the caller has write access to the calendar the event currently belongs to, but does not validate the destination calendar_id supplied in the request body. The model layer then persists the new calendar_id unconditionally. A regular user-role account can therefore create an event in their own calendar and immediately move it into any other user's calendar whose ID they know — bypassing the authorization check that create_event correctly performs. This vulnerability is fixed in 0.9.6.

A vulnerability was found in Campcodes Online Laundry Management System 1.0. It has been classified as problematic. Affected is an unknown function of the file admin_class.php. The manipulation of the argument type with the input 1 leads to improper authorization. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The identifier of this vulnerability is VDB-263940.

Authorization Bypass Through User-Controlled Key vulnerability in Dimitri Grassi Salon booking system salon-booking-system.This issue affects Salon booking system: from n/a through <= 10.9.

Sentry is a developer-first error tracking and performance monitoring platform. An authenticated user delete the user issue alert notifications for arbitrary users given a know alert ID. A patch was issued to ensure authorization checks are properly scoped on requests to delete user alert notifications. Sentry SaaS users do not need to take any action. Self-Hosted Sentry users should upgrade to version 24.9.0 or higher. There are no known workarounds for this vulnerability.

Sentry is a developer-first error tracking and performance monitoring platform. An authenticated user can mute alert rules from arbitrary organizations and projects with a know rule ID. The user does not need to be a member of the organization or have permissions on the project. In our review, we have identified no instances where alerts have been muted by unauthorized parties. A patch was issued to ensure authorization checks are properly scoped on requests to mute alert rules. Authenticated users who do not have the necessary permissions are no longer able to mute alerts. Sentry SaaS users do not need to take any action. Self-Hosted Sentry users should upgrade to version **24.9.0** or higher. The rule mute feature was generally available as of 23.6.0 but users with early access may have had the feature as of 23.4.0. Affected users are advised to upgrade to version 24.9.0. There are no known workarounds for this vulnerability.

Authorization Bypass Through User-Controlled Key vulnerability in masteriyo Masteriyo - LMS learning-management-system.This issue affects Masteriyo - LMS: from n/a through <= 1.11.4.

Authorization Bypass Through User-Controlled Key vulnerability in Dylan James Zephyr Project Manager.This issue affects Zephyr Project Manager: from n/a through 3.3.102.

Shopware is an open commerce platform. Prior to 6.6.10.18 and 6.7.10.1, the Store API endpoint /store-api/handle-payment in src/Core/Checkout/Payment/SalesChannel/HandlePaymentMethodRoute.php accepts a user-controlled orderId and forwards it to src/Core/Checkout/Payment/PaymentProcessor.php without verifying order ownership or guest-order authentication, allowing a normal customer or guest context to trigger the payment flow for another user's order while /store-api/order enforces the expected ownership model. This issue is fixed in versions 6.6.10.18 and 6.7.10.1.

The All Users Messenger WordPress plugin through 1.24 does not prevent non-administrator users from deleting messages from the all-users messenger.

Authorization Bypass Through User-Controlled Key in GitHub repository alextselegidis/easyappointments prior to 1.5.0.

The WCFM – Frontend Manager for WooCommerce plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 6.7.27 via the wcfm_product_archive due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with subscriber-level access and above, to archive arbitrary vendors' products, toggle the featured status on arbitrary listings, mark arbitrary WooCommerce orders as completed, and permanently delete arbitrary enquiries and bulk messages belonging to other vendors.

Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.5, an IDOR vulnerability exists in the Channels feature of Open WebUI, allowing any channel member to modify messages sent by other members (including administrators) within the same channel. In the update_message_by_id function, for group or dm type channels, only the caller's membership in the channel is checked via the is_user_channel_member function, without verifying message ownership. This allows any channel member to modify messages sent by other members within the same channel. This vulnerability is fixed in 0.9.5.

Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.5, Pin/Unpin is a write operation (modifies the message's is_pinned , pinned_by, pinned_at fields), but in standard channels it only checks read permission, allowing users with read-only access to pin/unpin any message. This vulnerability is fixed in 0.9.5.

The Community plugin 2.9.e-beta for Piwigo allows users to set image information on images in albums for which they do not have permission, by manipulating the image_id parameter.

OpenProject is open-source, web-based project management software. Prior to 17.3.2 and 17.4.0, OpenProject exposes a document update endpoint used to modify existing documents. The target document is loaded with visibility checks and then updated. During update, attacker-controlled attributes are applied to the persisted record before authorization is enforced. As a result, a user without :manage_documents in the source project can move and modify foreign project documents by setting project_id in a single PATCH request. This vulnerability is fixed in 17.3.2 and 17.4.0.

The Blog2Social: Social Media Auto Post & Scheduler plugin for WordPress is vulnerable to authorization bypass through user-controlled key in all versions up to, and including, 8.8.3. This is due to the plugin's AJAX handlers failing to validate that the user-supplied 'b2s_id' parameter belongs to the current user before performing UPDATE and DELETE operations. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify, reschedule, or delete other users' scheduled social media posts.

The School Management System – WPSchoolPress plugin for WordPress is vulnerable to Privilege Escalation due to a missing capability check on the wpsp_UpdateTeacher() function in all versions up to, and including, 2.2.16. This makes it possible for authenticated attackers, with teacher-level access and above, to update arbitrary user details including email which makes it possible to request a password reset and access arbitrary user accounts, including administrators.

FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.214, the Change Customer modal exposes a “Create a new customer” flow via POST /customers/ajax with action=create. Under limited visibility, the endpoint drops unique-email validation. If the supplied email already belongs to a hidden customer, Customer::create() reuses that hidden customer object and fills empty profile fields from attacker-controlled input. Version 1.8.214 fixes the vulnerability.

EspoCRM is an open source customer relationship management application. Prior to 9.3.5, a business logic flaw (Broken Access Control) in EspoCRM 9.3.3 allows low-privileged users to pin arbitrary notes without having the required edit permissions for the parent object. Due to a "write first, authorize later" execution flaw in the backend API, even though the server correctly returns a 403 Forbidden error, the targeted note's pinned status is already persistently modified in the database. The root cause lies in the server-side processing of the POST /api/v1/Note/{id}/pin endpoint. In application/Espo/Tools/Stream/Api/PostNotePin.php, the process() method first calls getNote($id) before calling checkParent($note). This vulnerability is fixed in 9.3.5.

The BadgeOS plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 3.7.1.6. This is due to improper validation and authorization checks within the badgeos_update_steps_ajax_handler, badgeos_update_award_steps_ajax_handler, badgeos_update_deduct_steps_ajax_handler, and badgeos_update_ranks_req_steps_ajax_handler functions. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to overwrite arbitrary post titles.

The MStore API plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.18.3. This is due to the update_user_profile() function in controllers/flutter-user.php processing the 'meta_data' JSON parameter without any allowlist, blocklist, or validation of meta keys. The function reads raw JSON from php://input (line 1012), decodes it (line 1013), authenticates the user via cookie validation (line 1015), and then directly iterates over the user-supplied meta_data array passing arbitrary keys and values to update_user_meta() (line 1080) with no sanitization or restrictions. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify arbitrary user meta fields on their own accounts, including sensitive fields like wp_user_level (to escalate to administrator-level legacy checks), plugin-specific authorization flags (e.g., _wpuf_user_active, aiowps_account_status), and billing/profile fields with unsanitized values (potentially enabling Stored XSS in admin contexts). Note that wp_capabilities cannot be directly exploited this way because it requires a serialized array value, but wp_user_level (a simple integer) and numerous plugin-specific meta keys are exploitable.

In CentOS-WebPanel.com (aka CWP) CentOS Web Panel 0.9.8.851, an insecure object reference allows an attacker to change the e-mail usage value of a victim account via an attacker account.

The BadgeOS plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 3.7.1.6. This is due to improper validation and authorization checks within the badgeos_delete_step_ajax_handler, badgeos_delete_award_step_ajax_handler, badgeos_delete_deduct_step_ajax_handler, and badgeos_delete_rank_req_step_ajax_handler functions. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to delete arbitrary posts.

An improper authorization vulnerability was identified in GitHub Enterprise Server that allowed a user with read access to a repository and write access to a project to modify issue and pull request metadata through the project. When adding an item to a project that already existed, column value updates were applied without verifying the actor's repository write permissions. This vulnerability was reported via the GitHub Bug Bounty program and has been fixed in GitHub Enterprise Server versions 3.14.24, 3.15.19, 3.16.15, 3.17.12, 3.18.6 and 3.19.3.

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.9.7. This is due to missing authorization checks in the `save_course_content_order()` private method, which is called unconditionally by the `tutor_update_course_content_order` AJAX handler. While the handler's `content_parent` branch includes a `can_user_manage()` check, the `save_course_content_order()` call processes attacker-supplied `tutor_topics_lessons_sorting` JSON without any ownership or capability verification. This makes it possible for authenticated attackers with Subscriber-level access or above to detach lessons from topics, reorder course content, and reassign lessons between topics in any course, including admin-owned courses, by sending a crafted AJAX request with manipulated topic and lesson IDs.

hoppscotch is an open source API development ecosystem. Prior to version 2026.2.1, the DELETE /v1/access-tokens/revoke endpoint allows any authenticated user to delete any other user's PAT by providing its ID, with no ownership verification. This issue has been patched in version 2026.2.1.

GitLab has remediated an issue in GitLab CE/EE affecting all versions from 17.6 before 18.9.7, 18.10 before 18.10.6, and 18.11 before 18.11.3 that could have allowed an authenticated user with developer-role permissions to bypass PyPI package protection rules and upload restricted packages due to improper authorization checks.

LinkAce is a self-hosted archive to collect website links. In 2.1.0 and earlier, the processTaxonomy() method in LinkRepository.php allows authenticated users to attach other users' private tags and lists to their own links by passing integer IDs.

The User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 3.15.5 via the wppb_save_avatar_value() function due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with subscriber-level access and above, to reassign ownership of arbitrary posts and attachments by changing 'post_author'.

Craft is a content management system (CMS). Prior to 5.9.0-beta.1 and 4.17.0-beta.1, the "Duplicate" entry action does not properly verify if the user has permission to perform this action on the specific target elements. Even with only "View Entries" permission (where the "Duplicate" action is restricted in the UI), a user can bypass this restriction by sending a direct request. Furthermore, this vulnerability allows duplicating other users' entries by specifying their Entry IDs. Since Entry IDs are incremental, an attacker can trivially brute-force these IDs to duplicate and access restricted content across the system. This vulnerability is fixed in 5.9.0-beta.1 and 4.17.0-beta.1.

Discourse is an open source discussion platform. Versions prior to 2025.12.2, 2026.1.1, and 2026.2.0 have an IDOR (Insecure Direct Object Reference) in `ReviewableNotesController`. When `enable_category_group_moderation` is enabled, a user belonging to a category moderation group can create or delete their own notes on **any** reviewable in the system, including reviewables in categories they do not moderate. The controller used an unscoped `Reviewable.find` and the `ensure_can_see` guard only checked whether the user could access the review queue in general, not whether they could access the specific reviewable. Only instances with `enable_category_group_moderation` enabled are affected. Staff users (admins/moderators) are not impacted as they already have access to all reviewables. The issue is patched in versions 2025.12.2, 2026.1.1, and 2026.2.0 by scoping the reviewable lookup through `Reviewable.viewable_by(current_user)`. As a workaround, disable the `enable_category_group_moderation` site setting. This removes the attack surface as only staff users will have access to the review queue.

Kiteworks is a private data network (PDN). Prior to version 9.3.0, an Insecure Direct Object Reference (IDOR) vulnerability in Kiteworks Secure Data Forms allows an authenticated user to modify resources belonging to other users due to insufficient authorization checks on resource ownership. Upgrade Kiteworks to version 9.3.0 or later to receive a patch.

Mattermost Plugins versions <=11.3 11.0.3 11.2.2 10.10.11.0 fail to implement authorisation checks on comment block modifications, which allows an authorised attacker with editor permission to modify comments created by other board members. Mattermost Advisory ID: MMSA-2025-00559

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.

WeKan versions prior to 8.19 contain an insecure direct object reference (IDOR) in the card comment creation API. The endpoint accepts an authorId from the request body, allowing an authenticated user to spoof the recorded comment author by supplying another user's identifier.

Whisper Money is a personal finance application. Versions prior to 0.1.5 have an insecure direct object reference vulnerability. A user can update/create account balances in other users' bank accounts. Version 0.1.5 fixes the issue.

An insecure direct object reference (IDOR) in Online Market Place Site v1.0 allows attackers to modify products that are owned by other sellers.

Authorization Bypass Through User-Controlled Key vulnerability in Wptexture Image Slider Slideshow image-slider-slideshow allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Image Slider Slideshow: from n/a through <= 1.8.

The Jeg Elementor Kit plugin for WordPress is vulnerable to authorization bypass in various AJAX actions in versions up to, and including, 2.5.6. Authenticated users can use an easily available nonce value to create header templates and make additional changes to the site, as the plugin does not use capability checks for this purpose.

ONTAP versions 9.16.1 prior to 9.16.1P9 and 9.17.1 prior to 9.17.1P2 with snapshot locking enabled are susceptible to a vulnerability which could allow a privileged remote attacker to set the snapshot expiry time to none.

The Booking Calendar plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 10.14.14 via the handle_ajax_save function due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Subscriber-level access and above, and booking permissions granted by an Administrator, to modify other users' plugin settings, such as booking calendar display options, which can disrupt the booking calendar functionality for the targeted user.

The Wicked Folders – Folder Organizer for Pages, Posts, and Custom Post Types plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.1.0 via the delete_folders() function due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Contributor-level access and above, to delete arbitrary folders created by other users.

A vulnerability was detected in Craft CMS up to 4.18.0.1. Affected is the function actionReorderSets of the file src/controllers/GlobalsController.php of the component reorder-sets Endpoint. The manipulation results in authorization bypass. The attack can be executed remotely. Upgrading to version 4.18.1 is able to address this issue. The patch is identified as 9bd05c91e6a7e6da5e949ec41a31c220c059aa04. The affected component should be upgraded.

The Meow Gallery plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the REST API endpoint /wp-json/meow-gallery/v1/save_shortcode in all versions up to, and including, 5.4.4 This makes it possible for authenticated attackers, with Author-level access and above, to arbitrarily create or overwrite existing gallery shortcode records by supplying a user-controlled id value. The endpoint performs database update operations without verifying that the requesting user is authorized to modify the referenced gallery record or create their own.

The Document Embedder – Embed PDFs, Word, Excel, and Other Files plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.0.4. This is due to the plugin not verifying that a user has permission to access the requested resource in the 'bplde_save_document_library', 'bplde_get_single', and 'bplde_delete_document_library' AJAX actions. This makes it possible for authenticated attackers, with Author-level access and above, to read, modify, and delete Document Library entries created by other users, including administrators, via the 'id' parameter.
