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 authentication in the StudentPopupDetails_EmergencyContactDetails method in IDAttend’s IDWeb application 3.1.052 and earlier allows extraction of sensitive student data by unauthenticated attackers.
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 confidenceThe IDAttend IDWeb application version 3.1.052 and earlier contains a missing authentication vulnerability in the StudentPopupDetails_EmergencyContactDetails method, allowing unauthenticated remote attackers to directly access sensitive student data including emergency contact information without any credentials or prior authentication.

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 IDAttend IDWeb installationSearch for IDAttend IDWeb in installed applications or check web server directories for IDWeb application files (look for files named idweb, idattend, or related web application directories)Affected if IDAttend IDWeb is installed on the system
-
Determine installed versionLocate version information in application files: check version.txt, about page, or application configuration files within the IDWeb installation directory. Compare against 3.1.052Affected if Installed version is 3.1.052 or earlier
-
Verify web service is accessibleConfirm the IDWeb web application is running and accessible via HTTP/HTTPS. Note the base URL of the applicationAffected if The IDWeb application is running and network-accessible
-
Test vulnerable endpoint accessAttempt to access the StudentPopupDetails_EmergencyContactDetails endpoint directly without authentication. Try common URL patterns such as: /StudentPopupDetails_EmergencyContactDetails, /Student/EmergencyContactDetails, or variations using the application's base pathAffected if The endpoint returns student emergency contact data without requiring login credentials
-
Inspect response for sensitive dataExamine the HTTP response from the unauthenticated endpoint request for presence of student names, phone numbers, addresses, or other emergency contact informationAffected if Unauthenticated request returns readable student emergency contact data
If IDAttend IDWeb version 3.1.052 or earlier is running and the StudentPopupDetails_EmergencyContactDetails endpoint returns student data without authentication, the environment is affected by this CVE.
