CVE-2026-57266
HighCVSS 8.3Exploitation Probability (EPSS)
Low risk12th percentile — higher than 12% of all known CVEs
Summary
The GeoWebPlayer (Web Plugin/WS Player) addon for GeoVision software (GV-VMS, GV-Cloud) contains an out-of-bounds array access vulnerability in the 2wayAudio command. The WebSocket server accepts commands from localhost, and the 'index' value is not validated, allowing access to memory beyond the intended range.
Risk Assessment
An attacker on the local host can exploit this vulnerability to gain unauthorized access to critical memory sections, potentially leading to privilege escalation or arbitrary code execution in the application context.
Recommendation
Immediately update GeoWebPlayer to the latest version provided by GeoVision 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. #### 2wayAudio command index-out-of-bound
