CVE-2026-83663

HighCVSS 8.7/10Last modified Oct 2, 2026

Description

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.
