CVE-2026-57265
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. #### audio 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 confidenceThe GeoWebPlayer websocket server accepts commands from localhost that include an index parameter used to access arrays, but lacks bounds validation. This allows out-of-bounds array access, potentially enabling memory corruption or arbitrary code execution via the exposed critical sections and function calls.

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.
-
Verify GeoWebPlayer installationIdentify whether the GeoWebPlayer addon or component is present in the environment. Check product documentation or installed components list for GeoWebPlayer.Affected if GeoWebPlayer is installed and the websocket server feature is available.
-
Confirm websocket server is activeDetermine if the GeoWebPlayer websocket server is currently running and listening for connections. Inspect running services or process list for the websocket component.Affected if The websocket server is actively running and accepting connections.
-
Check localhost command acceptanceVerify whether the websocket interface accepts commands from localhost sources without requiring authentication or proper index validation.Affected if The websocket server accepts indexed commands from localhost without bounds checking on the index parameter.
A system is affected if GeoWebPlayer is installed with its websocket server running and accepting indexed commands from localhost without validating array index bounds.

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 dataDisable the GeoWebPlayer addon if not required, or implement proper index range validation on all websocket commands before array access to prevent out-of-bounds reads/writes.
