Overview

@a2ui/lit is an A2UI Lit Library

Affected versions of this package are vulnerable to Improperly Controlled Modification of Dynamically-Determined Object Attributes via the Root.renderComponentTree function in src/0.8/ui/root.js of the Renderer component, where an attacker can supply manipulated input that causes dynamically-determined object attributes to be set without proper validation. This can be exploited remotely by an authenticated user with low privileges, requiring user interaction to trigger the affected code path.
