CVE-2026-52751 | Ghidra before 12.1 contains an unsafe deserialization vulner… | CVSS 8.8 HIGH

Description

Ghidra before 12.1 contains an unsafe deserialization vulnerability in client-side Shared-Project RMI connection code that allows unauthenticated remote code execution. Attackers can craft a malicious project file with a ghidra:// URL that, when opened via File → Open Project, deserializes untrusted objects using a Jython 2.7.4 gadget chain to execute arbitrary commands.
