Miggo AIRoot Cause Analysis

The vulnerability stems from two key flaws: 1) Hub::inflate's lack of decompression size validation before length checks (allowing compressed small payloads to expand beyond limits), and 2) WebSocketImpl's failure to handle inflation errors. The patch adds a 16MB inflation limit in Hub::inflate and error checks in handleFragment, confirming these were the vulnerable points. The functions' roles in decompression and message processing directly align with the described exploit flow.
