CVE-2025-34293
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 · uneditedGN4 Publishing System versions prior to 2.6 contain an insecure direct object reference (IDOR) vulnerability via the API. Authenticated requests to the API's object endpoints allow an authenticated user to request arbitrary user IDs and receive sensitive account data for those users, including the stored password and the account's security question and answer. The exposed recovery data and encrypted password may be used to reset or take over the target account.
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 · high confidenceGN4 Publishing System prior to version 2.6 has an IDOR vulnerability in its API where authenticated users can access arbitrary user accounts by manipulating user IDs in API requests. This exposes sensitive data including encrypted password hashes and security question/answer pairs, enabling account takeover of targeted users.

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.
-
Identify installed GN4 Publishing System versionLocate the version file or check the product's about/status page, or query the API for version information if exposedAffected if The installed version is prior to 2.6 (e.g., 2.5.x, 2.4.x, etc.)
-
Confirm API endpoints are accessibleAttempt to access common API paths such as /api/users, /api/user/:id, or /api/v1/users, using HTTP requests with valid authenticationAffected if API endpoints respond and accept requests from authenticated users
-
Test for IDOR via user ID manipulationUsing an authenticated session, make API requests to user endpoints while varying the user ID parameter (e.g., /api/users/1, /api/users/2) to see if data from other users is returnedAffected if Requests with different user IDs return data for users other than the authenticated user, indicating missing authorization checks
-
Verify sensitive data exposureExamine API responses for user records to confirm whether encrypted password hashes, security questions, or security answers are exposed in the responseAffected if API responses include password hash fields, security question/answer fields, or other sensitive user data for users other than the authenticated user
If the GN4 Publishing System version is below 2.6 and the API returns data for arbitrary user IDs without proper authorization, the environment is affected by CVE-2025-34293.

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 dataUpdate to GN4 Publishing System version 2.6 or later, which should include proper authorization checks to prevent unauthorized access to user data via API endpoints.
