CVE-2026-1363
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 · uneditedIAQS and I6 developed by JNC has a Client-Side Enforcement of Server-Side Security vulnerability, allowing unauthenticated remote attackers to gain administrator privileges by manipulating the web front-end.
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 confidenceThis is a Client-Side Enforcement of Server-Side Security vulnerability in IAQS and I6 web applications developed by JNC. The application relies on client-side checks (likely JavaScript or HTML form controls) to enforce security policies, which can be bypassed by manipulating the web front-end. This allows unauthenticated remote attackers to escalate privileges to administrator level.

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 IAQS or I6 web applications are deployedReview your installed web applications and confirm whether IAQS or I6 applications developed by JNC are present in your environmentAffected if IAQS or I6 web application from JNC is present in the environment
-
Determine the installed version of IAQS or I6Check the application version through the web interface, configuration files, or software inventory. Compare against any available version information from JNCAffected if Running any version of IAQS or I6 where the version cannot be verified as patched
-
Inspect client-side scripts for security validationReview JavaScript files, form validation scripts, and HTML5 validation attributes in the web application front-end. Identify any security-critical functions that rely solely on client-side logic such as role checks, permission validation, or administrative action controlsAffected if Security enforcement logic (role verification, authorization checks, privilege escalation prevention) is implemented only in client-side code (JavaScript, HTML forms)
-
Test for server-side authorization on administrative functionsIntercept web requests using a proxy tool (such as Burp Suite or OWASP ZAP) and attempt to access administrative endpoints or trigger privileged actions by modifying or removing client-side validation controls (hidden fields, disabled buttons, role parameters)Affected if Administrative operations or privilege escalation actions succeed when client-side checks are bypassed but server-side validation is absent or insufficient
The environment is affected if IAQS or I6 is deployed and relies on client-side validation for security-critical operations such as privilege escalation prevention, with missing or inadequate server-side authorization checks.

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 server-side authorization and authentication checks for all sensitive operations; remove reliance on client-side validation for security enforcement and audit all endpoints for proper server-side access controls.
