CVE-2026-83663
Published:October 02, 2026
Updated:October 09, 2026
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.
