CVE-2026-118271 Details
Description
A security vulnerability has been detected in a2ui-project a2ui up to 0.10.6. This impacts an unknown function of the file renderers/web_core/src/v0_9/rendering/data-context.ts of the component data-context Resolver. Such manipulation leads to resource consumption. The attack may be performed from remote. The exploit has been disclosed publicly and may be used. The name of the patch is eb314e14fabd29cfb4a74e1202afc4fe2081efa2. Applying a patch is advised to resolve this issue.
A vulnerability allowing uncontrolled resource consumption has been identified in the A2UI project, specifically in versions through 0.10.6. The issue arises within the data-context resolver, where the handling of function call arguments can lead to excessive memory use and processing delays. This occurs because the resolver processes raw argument data before it is validated, creating unnecessary reactive components that burden the application's performance. The vulnerability can be exploited remotely by sending a crafted message through the A2UI protocol, causing the application to generate and maintain a large number of reactive nodes, which can significantly slow down UI updates and increase memory usage.
Users are advised to update to A2UI version 0.10.7 or later, where this vulnerability has been addressed.
