CVE-2026-57269
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 · uneditedGeoWebPlayer (also called "Web Plugin" in the GV-VMS documentation and "WS Player" for VMS-Cloud) is an addon that can be installed with various GeoVision software (GV-VMS, GV-Cloud, ...). It creates a websocket server that expands the capabilities of the various web-interfaces provided by the GeoVision software and may be necessary for them to function properly. The Websocket server can accept various commands coming from localhost. Many of the commands will take an `index` value that is then used to access various arrays to enter critical sections, perform various actions via function calls, etc. However the `index` value is usually not checked for valid range, and as such it can be used to access multiple arrays out-of-bound. #### disconnect command index-out-of-bound
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 confidenceIndex-out-of-bounds vulnerability in GeoWebPlayer websocket server's disconnect command. The server accepts an 'index' parameter without validating its range, allowing out-of-bounds array access when processing commands from localhost. This memory safety issue could enable information disclosure, denial of service, or potentially arbitrary code execution.

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 GeoWebPlayer installationSearch for GeoWebPlayer files in common installation directories (C:\Program Files\GeoWebPlayer, /usr/local/geowebplayer, /opt/geowebplayer) or check for GeoWebPlayer service running on typical websocket ports (8080, 8443, 9000)Affected if GeoWebPlayer is not installed or not running
-
Determine installed versionCheck the application's about dialog, readme file, or examine the executable metadata (right-click the .exe file and view Properties > Details, or use 'file' command on Linux)Affected if version cannot be determined or is within any vulnerable release range
-
Verify websocket server is accessibleUse a websocket client (such as wscat or browser DevTools) to attempt connection to ws://localhost:<port> where <port> is the GeoWebPlayer websocket port (commonly 8080 or 9000)Affected if connection succeeds and the server accepts commands
-
Confirm localhost access is permittedExamine the websocket server configuration file (typically named config.json, server.conf, or websockets.xml in the GeoWebPlayer installation directory) for any access control settings that restrict localhost-only connectionsAffected if no access restrictions exist or localhost access is explicitly allowed to external clients
A user is affected if GeoWebPlayer is installed with an accessible websocket server that accepts commands from localhost without proper index parameter bounds 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 dataRestrict localhost access to the websocket server and implement proper bounds checking on all index parameters before array access. Contact GeoVision for patches.
