CVE-2026-83663 · Apache Thrift: TFramedTransport and THeaderTransport re-enter Read once per frame that carries no payload (Go)

This page contains facts from public vulnerability sources. Check the original advisory before updating.

Uncontrolled Recursion vulnerability in Apache Thrift go bindings. Both Go transports satisfy a read out of a buffered frame and, when that frame yields no payload bytes, read the next frame and call `Read` again instead of looping. A peer produces such a frame for 4 bytes in `TFramedTransport` (a declared size of zero) or 18 bytes in `THeaderTransport` (a header block that fills the frame), so nothing bounds the depth. The Go stack limit is reached as a `fatal error`, which `recover()` cannot catch, so the whole process dies. This issue affects Apache Thrift: before 0.25.0. Users are recommended to upgrade to version 0.25.0, which fixes the issue.
