CVE-2026-55768
Full vulnerability record from the local CVENow database.
Description
GoAccess is a real-time web log analyzer and interactive viewer that runs in a terminal in *nix systems or through the browser. Prior to version 1.11, the built-in WebSocket server narrows a 64-bit extended frame length into the signed 32-bit WSFrame.payloadlen field before enforcing the maximum frame size, allowing an unauthenticated remote client to bypass the guard and force an approximately 18-exabyte allocation request that terminates the process. This issue is fixed in version 1.11.

"value": "GoAccess es un analizador de registros web en tiempo real y visor interactivo que se ejecuta en una terminal en sistemas nix o a través del navegador. Antes de la versión 1.11, el servidor WebSocket integrado reduce una longitud de trama extendida de 64 bits en el campo WSFrame.payloadlen firmado de 32 bits antes de aplicar el tamaño máximo de trama, permitiendo que un cliente remoto no autenticado omita la protección y fuerce una solicitud de asignación de aproximadamente 18 exabytes que termina el proceso. Este problema está solucionado en la versión 1.11."
