CVE-2026-3824
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 · uneditedIFTOP developed by WellChoose has an Open redirect vulnerability, allowing authenticated remote attackers to craft a URL that tricks users into visiting malicious website.
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 confidenceIFTOP by WellChoose contains an open redirect vulnerability that allows authenticated remote attackers to craft malicious URLs containing arbitrary redirect targets. When users click these crafted links, they are redirected to attacker-controlled websites, enabling phishing and credential theft attacks.

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 the installed version of IFTOP or Wellchoose Organization Portal SystemCheck the application version displayed in the portal interface, or query the system configuration files, package metadata, or software inventory for the exact version numberAffected if The version is less than iftop_p4_181 (any version before this release)
-
Confirm authentication mechanisms are enabledVerify that user authentication is configured and active for the portal system, as the vulnerability requires an authenticated attackerAffected if Authentication is enabled and users can log in to the portal
-
Locate redirect functionality in the applicationSearch the application source code or configuration for redirect, URL forwarding, or location header parameters that accept user-supplied redirect targetsAffected if The application contains redirect logic that accepts dynamic URL parameters without strict allowlist validation
-
Test for open redirect parameter handlingInspect the application's handling of redirect parameters in HTTP requests or URL query strings, checking if arbitrary domains are accepted as redirect destinationsAffected if The redirect mechanism allows arbitrary external URLs to be specified and used as redirect targets without domain allowlist validation
-
Review URL validation logic for redirect parametersExamine the code or configuration responsible for validating redirect destinations, looking for allowlist or blocklist implementationsAffected if There is no strict allowlist validation enforcing that redirect destinations must belong to trusted domains
Your environment is affected if the installed IFTOP version is earlier than iftop_p4_181 and the application includes redirect functionality accessible to authenticated users without proper URL allowlist validation.

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 strict URL validation using an allowlist approach for redirect parameters, and ensure all redirect destinations are validated against trusted domains before performing the redirect.
