CVE-2026-83663: CWE-674 Uncontrolled Recursion in Apache Software Foundation Apache Thrift
CVE-2026-83663 is an uncontrolled recursion vulnerability in the Go bindings of Apache Thrift before version 0.25.0. The issue arises when the Go transports read a buffered frame yielding no payload bytes and recursively call Read again without looping, leading to unbounded recursion. This causes the Go stack limit to be reached, resulting in a fatal error that terminates the process. The vulnerability is fixed in Apache Thrift version 0.25.0.
AI Analysis
Technical Summary
The vulnerability in Apache Thrift Go bindings involves uncontrolled recursion when reading frames with no payload bytes. Both Go transports read out a buffered frame and, if the frame yields no payload bytes, they recursively call Read instead of looping. A peer can produce such frames with zero declared size or a header block that fills the frame, causing unbounded recursion. This leads to the Go runtime stack limit being exceeded, causing a fatal error that crashes the process. The issue affects Apache Thrift versions before 0.25.0 and is resolved in version 0.25.0.
Potential Impact
Exploitation of this vulnerability causes the affected Apache Thrift Go process to crash due to a fatal stack overflow error. This results in denial of service as the process terminates unexpectedly. There is no indication of code execution or data compromise from the provided information.
Mitigation Recommendations
Users should upgrade Apache Thrift to version 0.25.0 or later, where this uncontrolled recursion issue is fixed. No other mitigation is indicated or required according to the vendor advisory.
