CVE-2026-55768: Allinurl Goaccess

High severity, CVSS 8.7. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Allinurl Goaccess: before 1.11 (fixed in 1.11)
