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 · uneditedUnauthenticated Broken Access Control in Salon booking system <= 10.30.25 versions.
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.

An attacker can exploit this flaw without any credentials to access functionality or data that should require proper authorization, likely gaining unauthorized access to administrative or privileged operations within the booking system.

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 Salon booking system is installedCheck your web server document roots or application directories for the Salon booking system files, typically by searching for files containing 'salon' or 'booking' in the application name, or checking known installation paths for this software.Affected if The Salon booking system software is present on the server
-
Determine the installed versionLocate the version file, about page, or configuration file within the Salon booking system installation that displays the software version number. This is often found in a README, version.php, or the admin dashboard.Affected if The installed version is 10.30.25 or any version number lower than 10.30.25
-
Verify the system is network-accessibleConfirm the Salon booking system web interface is reachable over the network by accessing its URL from a browser or command-line tool without providing any login credentials.Affected if The application is accessible without authentication over the network
-
Test for unauthenticated access to privileged functionsAttempt to access administrative endpoints, user data URLs, or privileged features directly without providing any credentials. Common paths to test include /admin, /dashboard, /settings, or API endpoints that should require authorization.Affected if You can access administrative interfaces, user data, or privileged functionality without providing any login credentials
You are affected if the Salon booking system is installed and the installed version is 10.30.25 or earlier, and the system allows unauthenticated access to functionality that should require 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 dataUpgrade the Salon booking system to a version newer than 10.30.25 to obtain the patched version with proper access control enforcement. If an update is unavailable, implement additional authentication and authorization controls at the application or web server layer.
