CVE-2026-42609
HighSummary
Grav is a file-based web platform. Prior to version 2.0.0-beta.2, a business logic vulnerability in the Grav Admin Panel allowed a low-privileged user to overwrite existing accounts, including the primary administrator account.
Risk Assessment
This vulnerability leads to a Denial of Service (DoS) on administrative functions and privilege de-escalation of the root account, which can result in serious management issues.
Recommendation
It is recommended to upgrade to version 2.0.0-beta.2 or later to mitigate this vulnerability and secure the system against potential attacks.

Original NVD description (English source)
Grav is a file-based Web platform. Prior to 2.0.0-beta.2, a business logic vulnerability in the Grav Admin Panel allows a low-privileged user (with only user creation permissions) to overwrite existing accounts, including the primary administrator. By creating a new user with a username that already exists, the system updates the existing account's metadata and permissions instead of rejecting the request. This leads to a Denial of Service (DoS) on administrative functions and Privilege De-escalation of the root account. This vulnerability is fixed in 2.0.0-beta.2.
