CVE-2026-54715

GoAccess is a real-time web log analyzer and interactive viewer that runs in a terminal in *nix systems or through the browser. In version 1.10.2, parse_browser assumes the matched browser token begins with Opera and moves a trailing version substring to match plus five, allowing a crafted User-Agent in a processed access log to write one to four attacker-influenced bytes beyond the heap allocation and corrupt or crash GoAccess. This issue is fixed in version 1.11.

Summary		(es) GoAccess es un analizador de registros web en tiempo real y un visor interactivo que se ejecuta en una terminal en sistemas nix o a través del navegador. En la versión 1.10.2, parse_browser asume que el token de navegador coincidente comienza con Opera y mueve una subcadena de versión final a la posición de coincidencia más cinco, permitiendo que un User-Agent manipulado en un registro de acceso procesado escriba de uno a cuatro bytes influenciados por el atacante más allá de la asignación de heap y corrompa o bloquee GoAccess. Este problema está solucionado en la versión 1.11.
