SCA: security update for getgrav/grav-plugin-api (GHSA-r945-h4vm-h736)

high Tenable Cloud Security Plugin ID 441204

Description

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

- Grav API Plugin is a RESTful API for Grav CMS that provides full headless access to your site's content,
media, configuration, users, and system management. Prior to 1.0.0-beta.15, an insecure direct object
reference and logic flaw in the Grav API plugin (UsersController::update) allows any authenticated user
with basic API access (api.access) to modify their own permission configuration. An attacker can exploit
this to escalate their privileges to Super Administrator (admin.super and api.super), leading to full
system compromise and potential RCE. This vulnerability is fixed in 1.0.0-beta.15. (CVE-2026-42843)

Solution

Update the getgrav/grav-plugin-api library and its related packages to version 1.0.0-beta.15 or later.
