CVE-2026-13131
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. #### connectInfo 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 · high confidenceGeoWebPlayer websocket server fails to validate the 'index' parameter in various commands before using it to access arrays. This allows an attacker with local access to the websocket server to read or write beyond array boundaries by providing out-of-range index values, potentially leading to memory corruption, information disclosure, or denial of service.

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 GeoWebPlayer is installedSearch for GeoWebPlayer software on the system using package managers, installed programs lists, or file system searches for GeoWebPlayer-related directories or executablesAffected if GeoWebPlayer is found installed on the system
-
Determine the installed versionLocate the GeoWebPlayer version information through the application's about dialog, version file, executable properties, or package manager listingAffected if The installed version matches or falls within an affected version range (compare to known vulnerable versions if available)
-
Verify the websocket server is enabledCheck GeoWebPlayer configuration files, running processes, or service settings to determine if the websocket server component is activeAffected if The websocket server is running and listening on a network interface
-
Check websocket access controlsExamine the websocket server configuration to determine authentication requirements and permitted client origins or IP addressesAffected if The websocket interface allows unauthenticated access or accepts connections from untrusted local processes
-
Assess local attack surfaceReview which local users or processes have network access to the websocket server port (typically localhost or local interface)Affected if Untrusted local users or processes can connect to the websocket server
The environment is affected if GeoWebPlayer with a vulnerable websocket server version is installed, the websocket interface is accessible, and untrusted local actors can interact with it without proper validation of index parameters.

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 access to the localhost websocket interface to trusted local processes only, and implement proper bounds checking on all index parameters before array access. Consider network segmentation to limit local attack surface.
