GoAccess: Heap Out-of-Bounds Write in parse_browser()

Assigner: GitHub_M
Reserved: 15.06.2026 Published: 30.07.2026 Updated: 31.07.2026

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.
