NVD 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.

    🚨High - GoAccess WebSocket 64-bit Length Truncation DoS (CVE-2026-55768) GoAccess’ built-in WebSocket server parses the 64-bit extended frame length but truncates it into a signed 32-bit field before max-size enforcement. An unauthenticated remote client can send a crafted frame to bypass the size guard and force a huge allocation request, crashing the process (DoS). Non-WebSocket deployments aren’t affected. 👉Affected: goaccess < 1.11 | Upgrade to 1.11

    Post summary

    The post announces a new DoS vulnerability in GoAccess WebSocket due to length truncation, provides technical details and a mitigation to upgrade to version 1.11.
