CVE-2026-55777

GoAccess: Out-of-bounds heap read in parse_ios() via crafted User-Agent leads to remote crash/DoS PUBLISHED

Description (CNA)

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 1.11, the parse_ios() function uses an attacker-controlled keyword-to-OS offset as both the source offset and copy length for memmove, allowing a crafted User-Agent in a processed access log to read up to approximately 4 KB beyond the heap allocation and conditionally crash GoAccess. This issue is fixed in version 1.11.
