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.
