Root Cause Analysis
The vulnerability stems from uncontrolled resource consumption when processing HTTP bodies. The patches consistently add size limitations using http.MaxBytesReader
and io.LimitReader
across multiple components. Each identified function
was modified to constrain request/response body sizes, indicating they previously handled untrusted input without proper size validation. These functions directly process()
HTTP message bodies and would appear in stack traces when handling malicious large payloads. The ServiceBus
-related functions (processMessage
, Forward
) are particularly critical as they're explicitly mentioned in the vulnerability description.
