Authorization Bypass Through User-Controlled Key

When secondary user stores are configured, the implicit-association resolver incorrectly initializes from a secondary user store and bypasses the primary user store during search and uniqueness checks. This allows a subject to be associated with an unintended local account if the same lookup claim (e.g., username or email) exists in both the primary and a secondary store. If duplicate claim values exist across user stores, this issue can lead to identity confusion due to incorrect implicit associations when using an external Identity Provider (IDP). Legitimate user accounts in the primary user store may fail to associate correctly with their corresponding external IDP accounts, potentially restricting access if the secondary account has fewer privileges. Deployments are not affected if no secondary user stores are configured, implicit association is disabled, or claim values are globally unique.Show less

PeproDev WooCommerce Receipt Uploader (PeproDev WooCommerce Receipt Uploader WordPress plugin through 2.8.0 slug: pepro-bacs-receipt-upload-for-woocommerce), all versions up to and including 2.8.0 (latest on wordpress.org; no fixed version available at the time of writing), is vulnerable to unauthenticated missing-authorization / IDOR write. Requires WooCommerce.Show less

IBM Langflow OSS 1.0.0 through 1.10.3 contain an authorization bypass vulnerability in the MemoryComponent that allows authenticated users to access chat history of other users via session_id collision. The MemoryComponent.retrieve_messages and store_message methods filter on session_id without validating flow_id or user_id ownership, enabling cross-user information disclosure through multiple authenticated API endpoints including /api/v1/run/*, /api/v1/responses, and /api/v2/workflow/*. This vulnerability only affects multi-user deployments with LANGFLOW_AUTO_LOGIN=False.Show less

Improper Input Validation vulnerability in Apache Answer. This issue affects Apache Answer: through 2.0.1. A missing ownership check in the avatar-cleanup logic allows any authenticated user to delete other users' uploaded files by supplying their file URLs. Users are recommended to upgrade to version 2.0.2, which fixes the issue.Show less

Akaunting's shared download route (app/Http/Controllers/Common/Uploads.php::download, reachable at uploads/{id}/download behind only generic auth middleware) fetched the requested Media record by ID with no verification that it belonged to the requesting portal customer's own company, allowing any authenticated portal customer to download any other company's uploaded files by guessing or enumerating media IDs.Show less

Crater's NotePolicy checks only a blanket Bouncer ability (manage-all-notes / view-all-notes) with no company-ownership comparison, unlike InvoicePolicy and other sibling policies which additionally verify ->hasCompany(->company_id). Any authenticated user of one company can read, edit, or delete another company's notes by ID.Show less

Crater isolates data per company_id, and its Invoice/Estimate/Payment/Expense policies enforce both a Bouncer ability check and ->hasCompany(->company_id). CustomerPolicy's view/update/delete methods omit the company-ownership check entirely, checking only the blanket ability. Route-model-bound customer lookups and the bulk Customer::deleteCustomers method are similarly unscoped (self::find with no company filter).Show less

The Groundhogg — CRM, Newsletters, and Marketing Automation plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.5.2 via the GET /wp-json/gh/v4/contacts/<id> REST endpoint. The endpoint's permission callback checks only the role-level view_contacts capability and read_single() returns the full contact record by sequential integer ID without the object-level view_contact ownership check applied elsewhere in the codebase. This makes it possible for authenticated attackers holding view_contacts but not view_others_contacts — notably Groundhogg's built-in Sales Rep role, designed to see only its own contacts — to read any contact record on the site, including PII, contact meta, owner IDs, the admin edit URL, and (for contacts linked to a WordPress user) that user's full capability set.Show less

The DHL Shipping Germany for WooCommerce WordPress plugin before 4.0.1 does not perform any authorization check (no capability, nonce, login, or ownership check) on one of its shipping-label download endpoints, so an unauthenticated attacker can enumerate sequential ids and download every stored shipping label, each containing the customer's full name, complete postal address, and order reference.Show less

The MultiVendorX WordPress plugin before 5.0.11 does not verify that the requested store belongs to the current user in one of its REST API endpoints, allowing any vendor-level user to read other vendors' commission and financial data.Show less

A weakness has been identified in Ehco1996 django-sspanel up to 2023.12.26. This affects the function TicketDetailView of the file apps/sspanel/views.py of the component Support Ticket Handler. Executing a manipulation can lead to authorization bypass. The attack can be executed remotely. The vendor was contacted early about this disclosure but did not respond in any way. This vulnerability only affects products that are no longer supported by the maintainer.Show less

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.6 until 0.11.0, the sync cleanup endpoint authorized write access to the knowledge base in the URL but then acted on directory and file ids supplied in the request body without checking that those objects belonged to that knowledge base. A user with write access to one knowledge base could delete directories and remove file embeddings from another knowledge base, causing documents to drop out of retrieval results and breaking chat-with-file for targeted documents without disclosing contents. This issue is fixed in 0.11.0.Show less

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.3, several organization billing endpoints in packages/server/src/enterprise/routes/organization.route.ts and packages/server/src/enterprise/controllers/organization.controller.ts accept attacker-controlled Stripe subscriptionId values without verifying that the identifier belongs to the authenticated user's organization. An authenticated attacker can perform unauthorized Stripe subscription operations on other tenants, including changing subscription plans or modifying seat quantities, resulting in financial impact and service disruption. This issue is fixed in 3.1.3.Show less

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.3, the unauthenticated POST /api/v1/prediction/:id endpoint accepted an overrideConfig object and unconditionally spread it into internal flowConfig and flowData objects in packages/server/src/utils/buildChatflow.ts and packages/server/src/utils/index.ts without checking apiOverrideStatus. This allowed unauthenticated attackers to inject arbitrary properties into the flow execution context of any public chatflow, overwrite values such as chatId, sessionId, and chatHistory, and control values resolved through $flow.* template variables consumed by flow nodes. This issue is fixed in version 3.1.3.Show less

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.3, the OAuth2 token refresh endpoint POST /api/v1/oauth2-credential/refresh/:credentialId is unauthenticated by design and performs a server-side HTTP request to the credential-controlled accessTokenUrl without SSRF protections. Runtime validation confirmed that the endpoint was reachable without authentication, triggered outbound POST requests to an attacker-controlled server, reflected the full remote response body to the caller through tokenInfo, and sent client_id, client_secret, grant_type=refresh_token, and refresh_token in the request body. This issue is fixed in version 3.1.3.Show less

The Brizy WordPress plugin before 2.8.19 does not properly verify authorization on the object being modified before updating a template's type meta, validating a request parameter that is different from the one used in the write operation, allowing users with Contributor-level access and above to change the template-type assignment of templates owned by other users.Show less

A vulnerability was found in diaowen DWSurvey up to 6.14.0. Impacted is the function in DwDeisgnSurveyController.devSurvey. of the file /api/dwsurvey/app/v6/dw-design-survey/dev-survey.do of the component Survey Handler. The manipulation results in authorization bypass. The attack can be launched remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.Show less

Misskey is an open source, federated social media platform. Versions 2025.3.2 and later, but prior to 2026.5.4, contain a vulnerability where a lack of proper permission checks allows access to certain data points from the Direct Messages (formerly Chat) feature, regardless of account permissions. This vulnerability occurs whether or not federation is enabled. Notes created with "specified" visibility (formerly "direct" visibility) are not affected. This issue has been fixed in version 2026.5.4.Show less

A vulnerability was identified in jeequan jeepay up to 3.2.9. This vulnerability affects the function WebSecurityConfig of the file jeepay-manager/src/main/java/com/jeequan/jeepay/mgr/ctrl/sysuser/SysLogController.java of the component PreAuthorize Handler. The manipulation leads to authorization bypass. The attack may be initiated remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.Show less

Admidio before 5.0.11 contains an insecure direct object reference vulnerability in the save_temporary mode of mylist_function.php that allows authenticated users to hijack list configurations. Attackers can enumerate global list UUIDs and overwrite admin-curated global lists or other users' private lists by supplying a list_uuid parameter, transferring ownership and demoting global lists to personal configurations.Show less
