CVE-2026-57267Network attack vector

Code execution via unchecked snapshot array index

Published Jul 2, 2026 · Updated Jul 2, 2026

Out-of-bounds reads in GeoVision GeoWebPlayer 1.1.1.0 allow remote attackers to execute arbitrary code via a crafted WebSocket message. The snapshot handler uses an unchecked message index to enter crit_sections and later reads a release-function pointer beyond the array bounds. Exploitation requires the Windows add-on to be running and a user to visit an attacker-staged webpage that can reach its localhost WebSocket server.
