CVE-2026-43871 (opens in a new tab)How to fix?
Upgrade thrift to version 0.24.0 or higher.
Overview
thrift is a package containing Rust bindings for the Apache Thrift RPC system.
Affected versions of this package are vulnerable to Infinite loop in TCompactProtocol varint decoding, which reads continuation bytes without enforcing a maximum byte count. An attacker can hang the process deserializing a message by sending a TCompactProtocol varint whose continuation bit stays set across an unbounded run of bytes. This requires the application to deserialize attacker-controlled TCompactProtocol input.
