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 · uneditedMissing Authorization vulnerability in SePay team SePay Gateway allows Retrieve Embedded Sensitive Data. This issue affects SePay Gateway: from n/a through 1.1.20.
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 confidenceMissing Authorization (Broken Object Level Authorization) vulnerability in SePay Gateway allows unauthenticated or unauthorized users to retrieve embedded sensitive data through certain API endpoints. The application fails to properly validate user permissions before granting access to sensitive information.

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 SePay Gateway installationLocate the SePay Gateway application on your system. Check common installation directories or use system search tools to find files or services named 'SePay Gateway' or 'sepay'.Affected if SePay Gateway is not present on the system, then the vulnerability does not apply.
-
Determine installed versionLocate version information for the SePay Gateway installation. Check configuration files, about pages, or use command-line tools provided by the product (such as 'sepay version' or checking a version file in the installation directory).Affected if The installed version is 1.1.20 or earlier, making it potentially vulnerable.
-
Verify Gateway component is activeConfirm that the Gateway component is running or enabled. Check the service status, configuration files, or admin console to see if the Gateway component is active.Affected if The Gateway component is disabled or not in use, the specific vulnerability path may not be exposed.
-
Test sensitive data endpoint accessAttempt to access sensitive data endpoints within the Gateway without providing credentials or authorization tokens. Observe whether the system returns sensitive data without requiring authorization.Affected if The system returns sensitive or embedded data without any authorization check, confirming the vulnerability is present.
Your environment is affected if SePay Gateway is installed with the Gateway component enabled and the version is 1.1.20 or earlier, with sensitive endpoints accessible without authorization.

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 API endpoints that handle sensitive data. Validate user permissions and enforce access controls at every layer to ensure users can only access resources they are explicitly authorized for.
