CVE-2024-48915 (opens in a new tab)How to fix?
Upgrade agent_dart to version 1.0.0-dev.29 or higher.
Overview
agent_dart is an agent library built for Internet Computer, a plugin package for dart and flutter apps. Developers can build ones to interact with Dfinity's blockchain directly.
Affected versions of this package are vulnerable to Improper Certificate Validation due to improper handling in the _checkDelegation function. An attacker can impersonate a subnet and sign canister responses on behalf of another subnet by exploiting unchecked canister_ranges. Additionally, the lack of verification for the certificate's timestamp allows the certificate to effectively have no expiration time.
