SCA: security update for getgrav/grav (GHSA-38p6-h87p-r4cg)

medium Tenable Self-Hosted Container Security Plugin ID 477491

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-72701)

Solution

Update the getgrav/grav library and its related packages to version 2.0.16 or later.
