公告说明

Summary

During cleanup it is possible for a compressed request body to be decompressed into memory in one chunk.

Impact

An attacker may be able to send a compressed payload in specific situations that could be decompressed into memory, potentially leading to DoS (a zip bomb edge case).

Workaround

Disable compression if unable to upgrade.
