CWE-639

Authorization Bypass Through User-Controlled Key

The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.

Title
Cross-session PubSub topic injection via URL parameter in phoenix_storybook
Summary
Authorization Bypass Through User-Controlled Key vulnerability in phenixdigital phoenix_storybook allows cross-session PubSub topic injection via a URL query parameter. 'Elixir.PhoenixStorybook.Story.ComponentIframeLive':handle_params/3 in lib/phoenix_storybook/live/story/component_iframe_live.ex reads a PubSub topic directly from params["topic"] and broadcasts {:component_iframe_pid, self()} on it with no check that the topic belongs to the requesting session. The shared PhoenixStorybook.PubSub is used to coordinate playground LiveViews with their iframes: a playground subscribes to a session-specific topic and uses the received iframe pid to direct subsequent control messages (variation state, theme switches, extra-assign payloads) via send/2. Because the iframe trusts the query parameter, an attacker who loads /storybook/iframe/<story>?topic=<victim_topic> causes their iframe process pid to be announced on the victim's topic. The victim's playground then addresses its private messages to the attacker's iframe process. This issue affects phoenix_storybook from 0.4.0 before 1.1.0.

Title
AnythingLLM: Legacy mobile device tokens bypass multi-user workspace scoping after mode migration
Summary
AnythingLLM is an application that turns pieces of content into context that any LLM can use as references during chatting. Prior to 1.13.0, an approved mobile device token created in single-user mode can survive single-user -> multi-user migration even when the device record has userId = null. In multi-user mode, that stale token is still accepted by the mobile authentication middleware. Because no user is attached to the request, downstream mobile handlers fall back to unscoped data-access branches and return workspaces and workspace content without per-user filtering. This permits a pre-migration mobile token to enumerate a workspace assigned only to another user and retrieve victim-owned thread metadata and chat content in multi-user mode. This vulnerability is fixed in 1.13.0.

CVE-2026-47715 (GCVE-0-2026-47715)

Title
Bugsink: Issue event views can show an event from another project if its UUID is known
Summary
Bugsink is a self-hosted error tracking tool. Prior to 2.2.0, Bugsink issue event pages accept a direct event identifier from the URL and, in affected versions, look up that event without also requiring it to belong to the issue in the URL. This is a project-boundary authorization issue: a logged-in user with access to one project can view another project’s event data through an issue they are allowed to access. The affected views include the stacktrace, details, and breadcrumbs pages for an issue event. This vulnerability is fixed in 2.2.0.

Title
WCFM - WooCommerce Frontend Manager <= 6.7.25 - Insecure Direct Object References to Autenticated (Vendor+) Arbitrary Post/Product Manipulation
Summary
The WCFM – Frontend Manager for WooCommerce along with Bookings Subscription Listings Compatible plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 6.7.25 via multiple AJAX actions including `wcfm_modify_order_status`, `delete_wcfm_article`, `delete_wcfm_product`, and the article management controller due to missing validation on user-supplied object IDs. This makes it possible for authenticated attackers, with Vendor-level access and above, to modify the status of any order, delete or modify any post/product/page, regardless of ownership.

CVE-2026-5167 (GCVE-0-2026-5167)

Title
Masteriyo LMS <= 2.1.7 - Unauthenticated Authorization Bypass to Arbitrary Order Completion via Stripe Webhook Endpoint
Summary
The Masteriyo LMS – Online Course Builder for eLearning, LMS & Education plugin for WordPress is vulnerable to Authorization Bypass Through User-Controlled Key in versions up to and including 2.1.7. This is due to insufficient webhook signature verification in the handle_webhook() function. The webhook endpoint processes unauthenticated requests and only performs signature verification if both the webhook_secret setting is configured AND the HTTP_STRIPE_SIGNATURE header is present. Since webhook_secret defaults to an empty string, the webhook processes attacker-controlled JSON payloads without any verification. This makes it possible for unauthenticated attackers to send fake Stripe webhook events with arbitrary order_id values in the metadata, mark any order as completed without payment, and gain unauthorized access to paid course content.

CVE-2026-5199 (GCVE-0-2026-5199)

Vulnerability from cvelistv5 – Published: 2026-04-01 17:49 – Updated: 2026-04-01 18:24

Title
Cross Namespace Access via Batch Operation
Summary
A writer role user in an attacker-controlled namespace could signal, delete, and reset workflows or activities in a victim namespace on the same cluster. Exploitation requires the attacker to know or guess specific victim workflow ID(s) and, for signal operations, signal names. This was due to a bug introduced in Temporal Server v1.29.0 which inadvertently allowed an attacker to control the namespace name value instead of using the server's own trusted name value within the batch activity code. The batch activity validated the namespace ID but did not cross-check the namespace name against the worker's bound namespace, allowing the per-namespace worker's privileged credentials to operate on an arbitrary namespace. Exploitation requires a server configuration where internal components have cross-namespace authorization, such as deployment of the internal-frontend service or equivalent TLS-based authorization for internal identities. This vulnerability also impacted Temporal Cloud when the attacker and victim namespaces were on the same cell, with the same preconditions as self-hosted clusters.

Title
LatePoint <= 5.3.2 - Insecure Direct Object Reference to Unauthenticated Sensitive Financial Data Exposure via Sequential Invoice ID
Summary
The LatePoint plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.3.2. The vulnerability exists because the OsStripeConnectController::create_payment_intent_for_transaction action is registered as a public action (no authentication required) and loads invoices by sequential integer invoice_id without any access_key or ownership verification. This is in contrast to other invoice-related actions (view_by_key, payment_form, summary_before_payment) in OsInvoicesController which properly require a cryptographic UUID access_key. This makes it possible for unauthenticated attackers to enumerate valid invoice IDs via an error message oracle, create unauthorized transaction intent records in the database containing sensitive financial data (invoice_id, order_id, customer_id, charge_amount), and on sites with Stripe Connect configured, the response also leaks Stripe payment_intent_client_secret tokens, transaction_intent_key values, and payment amounts for any invoice.

Mitigation

Phase: Architecture and Design

Description:

  • For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
Mitigation

Phases: Architecture and Design, Implementation

Description:

  • Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
Mitigation

Phase: Architecture and Design

Description:

  • Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
