The Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to and including 4.2.0. This is due to insufficient object-level authorization in the image deletion REST flow where the permission callback for DELETE /imagely/v1/images/{id} only checks 'NextGEN Manage gallery' permissions and does not enforce gallery ownership or 'NextGEN Manage others gallery' permissions. This makes it possible for authenticated attackers, with Subscriber-level privileges and 'NextGEN Manage gallery' capability, to delete gallery images belonging to other users as well as their associated image files from disk when deleteImg is enabled (default).

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Directus v10.13.0 allows an authenticated external attacker to modify presets created by the same user to assign them to another user. This is possible because the application only validates the user parameter in the 'POST /presets' request but not in the PATCH request. When chained with CVE-2024-6533, it could result in account takeover.

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 PressPrimer Quiz – AI Quiz Maker, Exam Builder & LMS Assessment Plugin plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.3.0 via the 'rule_id' parameter due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with custom-level access and above, to modify or delete quiz rules belonging to other teachers, resulting in unauthorized tampering of another user's quiz structure.

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.

The Kadence Blocks – Gutenberg Blocks for Page Builder Features plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to and including 3.7.7. This is due to a mismatch between the object used for authorization and the object actually accessed in the Optimize_Rest_Controller's create_item(), get_item(), delete_item(), and bulk_delete_items() endpoints — authorization is checked via current_user_can('edit_post'/'delete_post', $post_id) against the user-supplied post_id, while the storage layer keys analysis records on sha256($post_path) from a separately supplied, attacker-controlled post_path parameter, with no enforcement that post_path corresponds to post_id. This makes it possible for authenticated attackers, with Contributor-level access and above, to read or delete optimizer analysis records belonging to posts owned by other users by submitting their own post_id (which passes the capability check) together with the victim post's path.

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.

All versions of askbot before and including 0.12.2 allow an attacker authenticated with normal user permissions to modify the profile picture of other application users.This issue affects askbot: 0.12.2.

The Dokan: AI Powered WooCommerce Multivendor Marketplace Solution – Build Your Own Amazon, eBay, Etsy plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.0.3 via the change_order_status, add_order_note, delete_order_note, add_shipping_tracking_info, grant_access_to_download, and revoke_access_to_download AJAX handlers due to missing ownership validation on a user-controlled order ID key. This makes it possible for authenticated attackers, with custom vendor-level access and above, to modify the status of arbitrary orders, add attacker-controlled notes to any order (including customer-facing notes that trigger WooCommerce notification emails to buyers), delete any order note or WordPress comment by ID regardless of ownership, inject fake shipping tracking information on any order, and grant or revoke downloadable-product permissions on any order in the marketplace. Critically, nonce validity is not a barrier to exploitation: each of these AJAX handlers generates and embeds its nonce on the authenticated vendor's own dashboard order pages (e.g., /dashboard/orders/?order_id=OWN_ORDER_ID), which the attacker legitimately controls. The attacker harvests a valid nonce from their own order detail page and replays it against a victim order ID — the nonce only proves the request originates from a logged-in session, not that the order belongs to that vendor. This directly rebuts the prior rejection reasoning that 'users cannot generate valid nonces on command': vendor users can and do generate valid nonces on demand simply by loading their own dashboard pages. Source-code analysis confirmed the vulnerable code path is present and unpatched through version 5.0.1.

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).

The TeraWallet plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 1.4.3. This is due to insufficient validation of the user-controlled key on the lock_unlock_terawallet AJAX action. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to lock/unlock other users wallets.

The Qi Blocks plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.4.9 via the 'page_id' parameter due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with author-level access and above, to modify the stored Qi Blocks styles of arbitrary posts, templates, or widgets they do not own — including site-wide surfaces via the reserved 'template' and 'widget' page_id values — enabling unauthorized frontend defacement, content hiding, and degradation of any page on the site. The endpoint's permission_callback checks only the generic edit_posts and publish_posts capabilities, meaning any user with the built-in Author role satisfies the check regardless of post ownership.

A vulnerability was found in macrozheng mall up to 1.0.3. This vulnerability affects the function paySuccess of the file /order/paySuccess.

Khoj is a self-hostable artificial intelligence app. Prior to version 1.29.10, an Insecure Direct Object Reference (IDOR) vulnerability in the update_subscription endpoint allows any authenticated user to manipulate other users' Stripe subscriptions by simply modifying the email parameter in the request. The vulnerability exists in the subscription endpoint at `/api/subscription`. The endpoint uses an email parameter as a direct reference to user subscriptions without verifying object ownership. While authentication is required, there is no authorization check to verify if the authenticated user owns the referenced subscription. The issue was fixed in version 1.29.10. Support for arbitrarily presenting an email for update has been deprecated.

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.

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.
