Detailed vulnerability description
The vulnerability allows a remote user to disclose sensitive information.
The vulnerability exists due to insufficient verification of data authenticity in the Bot Framework serviceUrl validation in @openclaw/msteams when processing lower-trust caller or configured input paths. A remote user can provide crafted input that reaches the affected path to disclose sensitive information.
Only instances where the affected feature is enabled and reachable are vulnerable, and practical impact depends on whether lower-trust input can reach that path.
