Hashgraph Guardian through 3.5.0, fixed in commit ba8c566, contains a stored cross-site scripting vulnerability that allows authenticated users with the STANDARD_REGISTRY role to inject malicious scripts by submitting a crafted companyName value via the branding configuration API endpoint. Attackers can exploit the unsanitized innerHTML assignment in the branding service to execute arbitrary JavaScript in the browser of every authenticated user on every page load.
The Guardian is an innovative open-source platform that streamlines the creation, management, and verification of digital environmental assets. It leverages a customizable Policy Workflow Engine and Web3 technology to ensure transparent and fraud-proof operations, making it a key tool for transforming sustainability practices and carbon markets.
