medium Tenable Self-Hosted Container Security Plugin ID 441218

Description

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

 - Grav is a file-based Web platform. Prior to 2.0.0-beta.2, an authenticated user with page editing
 permissions can inject an executable JavaScript event-handler attribute into rendered image HTML through
 Grav's Markdown media action syntax. The issue is caused by Markdown image query parameters being
 converted into callable media actions. The public attribute() media method can be reached this way,
 allowing an editor to set an arbitrary HTML attribute name and value on the generated image element. This
 vulnerability is fixed in 2.0.0-beta.2. (CVE-2026-42841)

Solution

Update the getgrav/grav library and its related packages to version 2.0.0-beta.2 or later.
