Kerentanan Observable Timing Discrepancy. Skor CVSS 3.1 3.7 (Low) menurut vulncheck.com.

Deskripsi (NVD)

Grav CMS before 2.0.16 contains a timing vulnerability in Utils::verifyNonce() that uses non-constant-time string comparison with the === operator instead of hash_equals() for CSRF nonce validation. Attackers can measure response timing differences to recover valid nonce values byte-by-byte through multiple requests, weakening CSRF protection below its intended security margin.
