Title
Vikunja: Scoped API token can mint unrestricted OAuth session credentials
Summary
Vikunja is an open-source self-hosted task management platform. In version 2.3.0, a scoped API token limited to the `oauth.authorize` permission can call `POST /api/v1/oauth/authorize`, obtain an OAuth authorization code, and exchange the code at `POST /api/v1/oauth/token` for a normal bearer JSON Web Token (JWT) and refresh token. The resulting credentials are not restricted by the original API token's permissions, allowing access to routes outside its declared scope for the same user. Version 2.4.0 fixes the vulnerability.
Severity
8.1 (High)

Title
Zammad: Incorrect Authorization and Improper Privilege Management
Summary
Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2 and 7.1.0, this issue concerns a lack of discursive validation within the authorization cascade. It has been determined that the system-level enforcement of access restrictions during the initialization of new identity objects exhibits a discrepancy: Under specific conditions, the granular restrictions of the access key being used are overridden by the latent authorization authority of the parent account. Consequently, this means that the intended separation of functional areas is nullified, resulting in an uncontrolled expansion of administrative discretion. Due to this potential integrity breach of the entire trust environment, an immediate evaluation of the authorization hierarchies is imperative. Impact An attacker can create new administrator accounts despite token restrictions. This grants full access to all system data (tickets, customers, configuration) and allows the attacker to take complete control of the Zammad instance. Abuse Scenario The vulnerability stems from a lack of synergy between the token-based authorization logic and the target system's functional authorization hierarchy, which allows for iterative escalation of the privileged access context. This issue is fixed in versions 7.0.2 and 7.1.0.

Supabase Capgo - Unauthenticated Cross-Tenant Build-Time Accounting Poisoning via record_build_time RPC
Summary
Supabase Capgo before 12.128.2 contains an authorization bypass vulnerability in the SECURITY DEFINER record_build_time RPC function that allows unauthenticated attackers to insert arbitrary build-time records. Attackers can exploit this by calling POST /rest/v1/rpc/record_build_time with a public API key to poison billing and quota data for any organization, enabling resource exhaustion and cross-tenant billing manipulation.

Title
Capgo - Privilege Escalation via SECURITY DEFINER Function apply_usage_overage
Summary
Capgo before 12.128.2 contains a potential privilege escalation vulnerability in the public.apply_usage_overage SECURITY DEFINER function, which performs sensitive billing operations without enforcing internal authorization checks (no validation of auth.uid(), org membership, or check_min_rights). Because the function runs with the owner's privileges, it bypasses Row Level Security. If EXECUTE permission is available to the authenticated or anon roles (explicitly or via default privileges), an authenticated user could invoke it via Supabase RPC to manipulate billing data for arbitrary organizations, including unauthorized credit depletion and fraudulent overage event insertion.

Title
Capgo - Authorization Bypass in API Key Management via App-Limited Keys
Summary
Capgo before 12.128.2 contains an authorization bypass vulnerability in its public API key management handlers (get/put/delete/post). API keys created with mode=all but restricted to a single app via limited_to_apps are only checked for limited_to_orgs and not for limited_to_apps, so an app-scoped key can enumerate, update, and delete sibling API keys belonging to the same account that are outside its declared app scope, enabling tampering with account-level credentials.

Capgo - Scope Escalation via API Key Creation in /functions/v1/apikey
Summary
Capgo before 12.128.2 contains a scope escalation vulnerability in the POST /functions/v1/apikey endpoint that allows app-limited API keys to mint unrestricted keys by setting empty limits. Attackers with a compromised app-limited key can create an unrestricted key with org-wide access to resources like app listings and other protected endpoints.

Title
Capgo - Improper 2FA Enforcement Logic via Team Security Settings
Summary
Capgo before 12.128.2 contains an authentication logic flaw: a user with permission to manage team or organization security settings can enable mandatory two-factor authentication for all team members without first enabling 2FA on their own account. The application fails to verify the initiator's 2FA status before allowing the policy change, resulting in inconsistent security enforcement, potential administrative misuse, and lockout risk for team members.

Title
Snipe-IT: Improper Privilege Management
Summary
Snipe-IT is an IT asset/license management system. Prior to 8.6.0, UsersController::update() passes a missing permission request field through NormalizePermissionsPayloadAction and PreserveUnauthorizedPrivilegedPermissionsAction in a way that can overwrite a target user’s permissions with a sparse result, allowing an administrator updating another administrator, or a user with users.edit updating a regular account, to remove the target’s administrative or granular permissions. This issue is fixed in version 8.6.0.

Title
NextCRM has RBAC Bypass in MCP Product Tools that Allows Low-Privileged Users to Modify the CRM Product Catalog
Summary
NextCRM is open-source customer relationship management (CRM) software. The CRM product catalog is an organization-wide business object. Normal application server actions restrict product creation, update, and deletion to `manager` and `admin` roles. However, in version 0.12.1, the MCP product tools expose the same write operations through `/api/mcp/mcp` using user-generated Bearer tokens and do not enforce role checks. Any authenticated low-privileged user who can generate an MCP API token can create, modify, archive, or soft-delete products in the shared CRM product catalog. Version 0.12.3 contains a fix.

Title
Piccolo Admin: Privilege escalation - admin to superuser via session-token disclosure in GET /api/tables/sessions/.
Summary
Piccolo Admin is an admin interface and content management system for Python, built on top of Piccolo. Prior to 1.14.0, piccolo_admin/endpoints.py uses superuser_validators to block PUT, PATCH, DELETE, and POST requests by non-superusers but permits GET requests to configured user and session tables, while piccolo_api/session_auth/tables.py exposes SessionsBase.token because the token column is not secret. In deployments that add the Sessions and User tables to create_admin, a non-superuser administrator can call GET /api/tables/sessions/, obtain another user's live session token, replay it as the Cookie id value to impersonate a superuser, and permanently set superuser to true on the attacker's own row. This issue is fixed in version 1.14.0.

Mitigation MIT-1
Architecture and Design
Operation
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Mitigation MIT-48
Architecture and Design
Strategy: Separation of Privilege
Follow the principle of least privilege when assigning access rights to entities in a software system.
Mitigation MIT-49
Architecture and Design
Strategy: Separation of Privilege
Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
CAPEC-122: Privilege Abuse
An adversary is able to exploit features of the target that should be reserved for privileged users or administrators but are exposed to use by lower or non-privileged accounts. Access to sensitive information and functionality must be controlled to ensure that only authorized users are able to access these resources.
CAPEC-233: Privilege Escalation
An adversary exploits a weakness enabling them to elevate their privilege and perform an action that they are not supposed to be authorized to perform.
CAPEC-58: Restful Privilege Elevation
An adversary identifies a Rest HTTP (Get, Put, Delete) style permission method allowing them to perform various malicious actions upon server data due to lack of access control mechanisms implemented within the application service accepting HTTP messages.
