CVE-2025-43008
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDue to missing authorization check, an unauthorized user can view the files of other company. This might lead to disclosure of personal data of employees. There is no impact on integrity and availability.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is a broken access control vulnerability (Insecure Direct Object Reference) in a multi-tenant application where missing authorization checks allow an unauthorized user to access files belonging to other companies. The flaw enables cross-tenant file disclosure, potentially exposing employee personal data. The CVSS vector indicates confidentiality-only impact with no integrity or availability consequences.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm multi-tenant architecture in useReview application architecture documentation, database schema for tenant标识符字段, or configuration files that define tenant isolation settings. Look for tenant_id, company_id, or organization_id fields in the data model.Affected if The application supports multiple tenants (companies/organizations) sharing the same instance and stores files or data per tenant.
-
Identify file storage and access endpointsReview API endpoints or web routes that handle file uploads, downloads, or viewing. Check for endpoints that accept file IDs, paths, or names as parameters (e.g., /api/files/{fileId}, /download?file=filename).Affected if The application exposes endpoints that serve or provide access to stored files.
-
Test for missing authorization on file accessCreate two separate test tenant accounts. As Tenant A, obtain a valid file ID or path. Then, using Tenant B's authentication, attempt to access Tenant A's file by manipulating the file identifier in the request. Observe if the server returns the file content without authorization errors.Affected if A user from one tenant can retrieve files belonging to another tenant without receiving an authorization/permission denied error.
-
Inspect file access authorization logicReview the application source code or configuration for authorization checks in file retrieval functions. Look for code that validates the requesting user's tenant matches the file's owner tenant before returning file content.Affected if No tenant ownership verification exists in file access code paths, or authorization checks are missing/commented out.
-
Review access logs for cross-tenant file accessExamine application access logs, audit trails, or security event logs for requests where user_id/tenant_id does not match the owner of the accessed file_id or resource.Affected if Logs show successful file access requests where the requester and file owner have different tenant identifiers.
A user is affected if the application is multi-tenant and lacks proper tenant isolation checks, allowing one tenant's authenticated users to access another tenant's files by manipulating file identifiers in requests.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement and enforce authorization checks at all file access endpoints to verify the requesting user owns or has permission to access the requested file resource, ensuring proper tenant isolation is maintained.
