CVE-2026-118272 Details
Description
A vulnerability was detected in a2ui-project a2ui up to 0.10.6. Affected is the function DataContext.dispatchExpressionError of the file renderers/web_core/src/v0_9/rendering/data-context.ts of the component Error Handler. Performing a manipulation results in information exposure through error message. It is possible to initiate the attack remotely. The exploit is now public and may be used. The patch is named 8f149a1c7b0ce1fa8e93ac3adfa5fda960faeb01. It is suggested to install a patch to address this issue.
A vulnerability allowing information exposure through error messages has been identified in the A2UI project, specifically in versions prior to 0.10.6. The issue arises in the Error Handler component, within the 'DataContext.dispatchExpressionError' function. When certain errors occur during expression evaluation, the function improperly includes the full V8 stack trace in the error details. This stack trace can reveal sensitive information such as internal file paths and SDK line numbers. The vulnerability can be exploited remotely, and the disclosed stack trace can aid in targeted follow-on attacks by leaking the client's internal structure and version details.
Users are advised to update to A2UI version 0.10.6 or later, where this vulnerability has been fixed.
