Executive Summary

This vulnerability is an Insecure Direct Object Reference (IDOR) in the Grav CMS Admin Panel prior to version 1.8.0-beta.27. It allows low-privilege users to access sensitive information from other user accounts, such as admin email addresses and metadata, even though they cannot directly take over those accounts.

Impact Analysis

The vulnerability can expose sensitive information like admin email addresses and metadata to unauthorized users. This exposure increases the risk of phishing attacks, credential stuffing, and social engineering, potentially compromising user security indirectly.

Mitigation Strategies

Upgrade Grav CMS Admin Panel to version 1.8.0-beta.27 or later, as this version contains the fix for the IDOR vulnerability. Until the upgrade can be applied, restrict low-privilege user access to the Admin Panel to minimize exposure of sensitive information.
