CVE-2026-109326

HIGH 8.7

Published 2026-10-12 · Last modified 2026-10-18

Grav before 2.1.7 contains an information disclosure vulnerability because bundled nginx, lighttpd, IIS, and Caddy 2 configurations block .git only at document root. Unauthenticated attackers can request nested repositories such as user/.git to retrieve Git config, refs, and objects, reconstructing unpublished history or committed secrets.
