CVE-2026-18718Public exploit

Code execution via persisted Swift tool path

Published Aug 3, 2026 · Updated Aug 3, 2026

Arbitrary code execution in Ghidra before 12.1.3 allows attackers to run binaries through a crafted project’s Swift tool directory. SwiftDemanglerAnalyzer restores the persisted directory from project state, and SwiftNativeDemangler executes its resolved binary without integrity or signature verification. Opening or analyzing the crafted project must reach the Swift demangler path, after which the binary runs as the Ghidra process user.
