Ghidra contains an arbitrary code execution vulnerability in the Swift demangler analyzer that allows an attacker to execute arbitrary binaries by supplying a malicious Ghidra project with a crafted Swift tool directory path. When a victim opens the attacker-supplied project, SwiftDemanglerAnalyzer restores the persisted Swift binary directory from project state and SwiftNativeDemangler executes the resolved binary without integrity or signature verification, causing attacker-controlled executables to run under the Ghidra process user with no prompt or confirmation.
