CVE-2026-57269
HighCVSS 8.3Exploitation Probability (EPSS)
Low risk15th percentile — higher than 15% of all known CVEs
Summary
A vulnerability in GeoWebPlayer (Web Plugin/WS Player) for GeoVision software (GV-VMS, GV-Cloud) stems from missing validation of the 'index' value in the 'disconnect' command of the WebSocket server. This allows out-of-bounds array access, potentially leading to unexpected behavior or control flow hijacking.
Risk Assessment
An attacker on localhost can exploit this flaw to read or write beyond memory boundaries, potentially causing service disruption, data leakage, or privilege escalation within the system.
Recommendation
Immediately update GeoWebPlayer to the latest version provided by the vendor and restrict WebSocket server access to trusted local processes only.
Original NVD description (English source)
GeoWebPlayer (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
