Kerentanan Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') pada getgrav grav. Skor CVSS 3.1 4.8 (Medium) menurut NVD.

Deskripsi (NVD)

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.
