## How to fix

- Fixed in 0.25.0

## Technical details

The vulnerability is an allocation of resources without limits or throttling in Apache Thrift language bindings (C++, Java, Go, netstd, Python, Delphi). An attacker can trigger unbounded resource consumption, likely through network-based input, leading to denial of service. The vulnerability affects all versions before 0.25.0.

## Affected products

- Apache Thrift before 0.25.0
