CVE-2026-13131
HighCVSS 8.3Exploitation Probability (EPSS)
Low risk12th percentile — higher than 12% of all known CVEs
Summary
A vulnerability in GeoWebPlayer (Web Plugin) allows out-of-bounds array access via an uncontrolled 'index' parameter in the connectInfo command. Lack of index range validation enables an attacker from localhost to trigger unintended actions.
Risk Assessment
An attacker from localhost can exploit this flaw to escalate privileges or perform unauthorized operations, potentially leading to system integrity compromise and data leakage.
Recommendation
Immediately update GeoWebPlayer to the latest version that includes index range validation. Restrict websocket server access to trusted 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. #### connectInfo command index-out-of-bound
