CVE-2026-54715: Allinurl Goaccess

High severity, CVSS 7.1. EPSS: 0.4% 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. 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.

Affected products

• Allinurl Goaccess: from 1.10.2, before 1.11 (fixed in 1.11)
