CVE-2026-55768

HIGH

GoAccess WebSocket Server: Signed 32 bit truncation of the 64 bit frame length causes a remote pre-authentication denial of service

Title source: cna
STIX 2.1

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.
