CVE-2026-52756: Nsa ghidra path traversal vulnerability

Nsa · Ghidra

Ghidra before 12.2 contains an unauthenticated path traversal vulnerability in the IsfServer that accepts TCP connections and passes client-supplied namespace strings directly to filesystem operations without validation. Remote attackers can connect to port 54321 and send crafted protobuf messages with traversal sequences to enumerate filesystem paths and probe arbitrary files.
