CVE-2026-5783
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 · uneditedImproper neutralization of input during web page generation ('cross-site scripting') vulnerability in Beyaz Computer Software Design Industry and Trade Ltd. Co. CityPLus allows Reflected XSS. This issue affects CityPLus: before V24.29750.1.0.
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 confidenceReflected XSS vulnerability in CityPLus allows attackers to inject malicious scripts via unsanitized user input that gets reflected in web pages without proper encoding, potentially leading to session hijacking or credential theft.

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.
-
Confirm CityPLus web application is runningIdentify the CityPLus web application by reviewing hosted web applications, checking web server configurations, or accessing the application's login page or known endpoints. Look for CityPLus branding, error messages, or HTTP headers referencing CityPLus.Affected if CityPLus web application is publicly accessible or internally hosted
-
Determine installed CityPLus versionCheck the version by reviewing application footer, about page, or help sections. If administrative access is available, check admin panels or configuration files for version strings. Compare against known affected versions.Affected if Version cannot be determined or is below the fixed release (V24.29750.1.0)
-
Identify reflected URL parametersNavigate through CityPLus pages and observe URL parameters in the address bar (query strings after ?). Common areas include search fields, navigation parameters, ID values, or filter options. Note each parameter name and its behavior when modified.Affected if URL parameters are present and user-controllable
-
Test for reflected XSS via parameter injectionInsert a benign XSS test payload (such as <script>alert(1)</script> or "><img src=x onerror=alert(1)>) into each identified URL parameter and observe if the payload renders unencoded in the page source or triggers JavaScript execution.Affected if Injected script payload appears verbatim in HTML response or executes in the browser without encoding or sanitization
A user is affected if CityPLus is running and URL parameters reflect unsanitized input that executes as JavaScript in the browser.
