Ghidra < 12.1 - Remote Code Execution via Unfiltered RMI Deserialization in Shared Project Connection
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
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.
