CVE-2026-3966
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 · uneditedA vulnerability was detected in 648540858 wvp-GB28181-pro up to 2.7.4-20260107. Affected by this vulnerability is the function getDownloadFilePath of the file /src/main/java/com/genersoft/iot/vmp/media/abl/ABLMediaNodeServerService.java of the component IP Address Handler. The manipulation of the argument MediaServer.streamIp results in server-side request forgery. The attack may be launched remotely. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
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 confidenceThis is a Server-Side Request Forgery (SSRF) vulnerability in the wvp-GB28181-pro video management platform. The getDownloadFilePath function in ABLMediaNodeServerService.java accepts the MediaServer.streamIp parameter without proper validation, allowing remote attackers to induce the server to make arbitrary HTTP requests to internal or external resources.

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 wvp-GB28181-pro is installedSearch for the application installation directory or running process. Look for files named ABLMediaNodeServerService.java or the compiled class, or check for the wvp-GB28181-pro service running on common ports (such as 8080, 18080).Affected if The application wvp-GB28181-pro is found running or installed on the system
-
Determine the installed versionCheck the application's version information in the installation folder, pom.xml, or the running service banner. Common locations: /opt/wvp, /home/wvp, or the war/jar file name.Affected if The version cannot be determined or falls within an affected version range (compare your installed version to any official vulnerability advisory)
-
Verify the ABLMediaNodeServerService component is exposedIdentify if the ABLMediaNodeServerService.java component is accessible. Check the application's API endpoints or web service paths. Look for URLs containing 'ABLMediaNodeServerService' or related media server endpoints.Affected if The ABLMediaNodeServerService endpoint is accessible via HTTP/HTTPS
-
Check if MediaServer.streamIp parameter is controllableExamine the application's API parameters or configuration to determine if the MediaServer.streamIp parameter can be supplied via user input (query parameters, request body, or configuration). Review the getDownloadFilePath function handling.Affected if The streamIp parameter accepts user-controlled input without validation
You are affected if wvp-GB28181-pro is running and the ABLMediaNodeServerService endpoint is accessible with the MediaServer.streamIp parameter user-controllable.

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 allow-list validation for the MediaServer.streamIp parameter to ensure only permitted IP addresses or hostnames can be used, preventing the server from making requests to internal infrastructure or arbitrary external URLs.
