## Description

A flaw has been found in DecoCMS Mesh up to 1.0.0-alpha.31. Affected by this vulnerability is the function createTool of the file packages/sdk/src/mcp/teams/api.ts of the component Workspace Domain Handler. This manipulation of the argument domain causes improper access controls. The attack can be initiated remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been published and may be used. Upgrading to version 1.0.0-alpha.32 addresses this issue. Patch name: 5f7315e05852faf3a9c177c0a34f9ea9b0371d3d. It is recommended to upgrade the affected component.
