CVE-2026-78851Network attack vectorHinoki check available

Information disclosure via mediaDirFunc directory traversal

Published Oct 15, 2026 · Updated Oct 15, 2026

Directory traversal in GetGrav Grav 2.0.3 through 2.0.6 allows remote attackers to read sensitive information via mediaDirFunc(). The supplied record names GravExtension.php, but the faulty path operation could not be independently verified for this CVE. A similar upstream report requires Twig page-authoring access; that precondition and its file-access limits remain unverified for this record.
