CVE-2026-6666 is a null pointer dereference in PgBouncer versions before 1.25.2. PgBouncer can crash while processing a PostgreSQL server error response that omits the required SQLSTATE field. The flaw is reachable through malformed error handling from an upstream PostgreSQL server.

This repository is a small Python proof-of-concept/simulation of an insecure deserialization issue framed as CVE-2026-6666 affecting an XPC-style service. It contains two code files: 'vulnerable_xpc_service.py', which implements a local TCP server on localhost:8888 that deserializes untrusted plist data and executes the 'runCommand' field with subprocess.Popen(shell=True), and 'exploit_xpc.py', which crafts a plist payload and sends it to that service. The exploit capability is arbitrary command execution against the simulated service; the included payload runs 'id > /tmp/pwned.txt' to demonstrate success. The repository is not part of a known exploit framework and appears to be a standalone educational/demo exploit rather than a real weaponized exploit for native macOS/iOS XPC. Structure is minimal: LICENSE, README with usage instructions and vulnerability description, the exploit client, and the intentionally vulnerable server. The primary fingerprintable targets are the local TCP listener at localhost:8888 and the artifact file /tmp/pwned.txt created by the payload.
