Miggo AIRoot Cause Analysis
The vulnerability manifests in path traversal logic within set() and unset() functions. The patches add explicit checks to block modifications via 'proto', 'constructor', and 'prototype' path segments. In vulnerable versions, these functions would process malicious paths without validation, making them the direct entry points for prototype pollution. The profiler would show these functions handling attacker-controlled paths during exploitation.
