CVE-2026-7491
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 · uneditedSchool App developed by Zyosoft has an Insecure Direct Object Reference vulnerability, allowing authenticated remote attackers to modify a specific parameter to read and modify other users' data.
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 confidenceZyosoft School App contains an Insecure Direct Object Reference (IDOR) vulnerability where an authenticated attacker can manipulate a specific parameter (likely a user or record identifier) to read and modify data belonging to other users. The application fails to validate that the authenticated user has authorization to access or modify the referenced object.

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 if Zyosoft School App is installedSearch for Zyosoft School App in your installed applications, check for related services, or look for school-related web applications on your serverAffected if The application is present in your environment
-
Determine the installed versionCheck application metadata, installed packages, or the web interface footer/admin panel for version informationAffected if Version cannot be determined or is unknown
-
Verify authentication is enabledConfirm that user authentication is required to access the application - try accessing without credentials and check if login is enforcedAffected if Anonymous access is allowed to the application
-
Check for user-specific endpoints or parametersReview application traffic or API endpoints for patterns like userId, recordId, or similar parameters in URLs that directly reference objectsAffected if The application uses direct object references in URLs or API calls without indirect mapping
-
Test for IDOR vulnerabilityLog in with one user account, identify a request that references your own user/record data, then modify the identifier to point to a different user's data and observe if unauthorized access is grantedAffected if Modifying object identifiers allows access to other users' data
Your environment is affected if Zyosoft School App is installed and the application allows authenticated users to access or modify other users' data by manipulating object 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 proper authorization checks on all object references to verify the requesting user has permission to access or modify the specific resource. Replace direct object references with indirect references or add ownership validation before processing requests.
