CVE-2026-62230Public exploitNetwork attack vector

Unauthenticated file disclosure via case-sensitive rewrite rules

Published Jul 17, 2026 · Updated Jul 17, 2026

Information disclosure in Grav before 2.0.4 allows remote attackers to read sensitive files via case-varied HTTP requests. The shipped .htaccess and reference htaccess.txt rules omit the NC flag, so Apache compares blocked extensions case-sensitively. Exploitation requires Apache and a case-insensitive filesystem or mounted volume, exposing configuration data, API keys, credentials, or source files.
