CVE-2026-57267
HighCVSS 8.3Exploitation Probability (EPSS)
Low risk12th percentile — higher than 12% of all known CVEs
Summary
A vulnerability in GeoWebPlayer (Web Plugin/WS Player) allows out-of-bounds array access via improper validation of the 'index' value in the 'snapshot' command. An attacker from localhost can exploit this to perform unauthorized operations.
Risk Assessment
The risk includes potential system integrity compromise, data leakage, or service disruption, as an attacker can manipulate critical code sections without proper validation.
Recommendation
Immediately update GeoWebPlayer to the latest version and implement access restrictions to the websocket server for trusted hosts 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. #### snapshot command index-out-of-bound
