0 CVE-2026-42845 is a high-severity vulnerability in the Grav CMS form plugin (grav-plugin-form) versions prior to 9.1.0. It allows unauthenticated attackers to overwrite page content via crafted file uploads due to insufficient sanitization of uploaded filenames. This could enable an attacker to overwrite the page's own markdown (. md) files and potentially escalate privileges to super-admin through a subsequent save action. The vulnerability is fixed in version 9.1.0 by stripping path components from filenames and blocking critical page-content extensions regardless of configuration.
