The ACF to REST API plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.3.4. This is due to insufficient capability checks in the update_item_permissions_check() method, which only verifies that the current user has the edit_posts capability without checking object-specific permissions (e.g., edit_post($id), edit_user($id), manage_options). This makes it possible for authenticated attackers, with Contributor-level access and above, to modify ACF fields on posts they do not own, any user account, comments, taxonomy terms, and even the global options page via the /wp-json/acf/v3/{type}/{id} endpoints, granted they can authenticate to the site.

The Flexible Refund and Return Order for WooCommerce plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.0.38 via the save_refund_request() function. This makes it possible for authenticated attackers, with subscriber-level access and above, to submit refund requests for arbitrary orders that they do not own.

The Permalink Manager Lite plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'ajax_save_permalink' function in all versions up to, and including, 2.4.3.1. This makes it possible for authenticated attackers, with author access and above, to modify the permalinks of arbitrary posts.

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.

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.

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.

An authorization vulnerability exists within GitLab from versions 16.10 before 16.10.6, 16.11 before 16.11.3, and 17.0 before 17.0.1 where an authenticated attacker could utilize a crafted naming convention to bypass pipeline authorization logic.

The WP Job Portal – A Complete Recruitment System for Company or Job Board website plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.2.8 via the deleteUserPhoto() function due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Subscriber-level access and above, to remove profile photos from users accounts. Please note that this does not officially delete the file.

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.

A vulnerability was found in Abstrium Pydio Cells 4.2.0. It has been rated as problematic. Affected by this issue is some unknown functionality of the component Change Subscription Handler. The manipulation leads to authorization bypass. The exploit has been disclosed to the public and may be used. Upgrading to version 4.2.1 is able to address this issue. It is recommended to upgrade the affected component. VDB-230210 is the identifier assigned to this vulnerability.

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.

Insecure direct object references (IDOR) vulnerability in ExpressTech Quiz And Survey Master plugin <= 7.3.4 at WordPress allows attackers to change the content of the quiz.

The employee management page of Flygo contains an Insecure Direct Object Reference (IDOR) vulnerability. After being authenticated as a general user, remote attacker can manipulate the user data and then over-write another employee’s user data by specifying that employee’s ID in the API parameter.

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 Homey theme for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.4.4 via the 'homey_delete_user_account' action due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete other user's accounts.

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.

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.

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.

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.

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.

GitLab has remediated an issue in GitLab CE/EE affecting all versions from 17.10 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 delete protected container registry tags due to improper authorization checks.

CA API Developer Portal 4.3.1 and earlier contains an access control flaw that allows privileged users to perform a restricted user administration action.

The Charitable – Donation Plugin for WordPress – Fundraising with Recurring Donations & More plugin for WordPress is vulnerable to Insecure Direct Object Reference / Authorization Bypass leading to Arbitrary Attachment Deletion in versions up to, and including, 1.8.11.1 via the profile avatar update flow. This is due to the save_avatar() function in Charitable_Profile_Form calling wp_delete_attachment() on an attachment ID read from the user's 'avatar' meta without validating that the attachment is owned by the user, combined with Charitable_Data_Processor::process_picture() returning the raw posted value when no file is uploaded, allowing the 'avatar' user meta to be poisoned with any attacker-chosen attachment ID. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary attachments from the Media Library by performing a two-request chain (first poisoning the stored avatar meta value with a target attachment ID, then triggering deletion via a normal avatar upload).
