CVE-2026-52751: Deserialization of Untrusted Data in nationalsecurityagency ghidra
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.
AI Analysis
Technical Summary
CVE-2026-52751 is a high-severity vulnerability affecting Ghidra before version 12.1. It arises from unsafe deserialization in the client-side Shared-Project RMI connection code. An attacker can create a malicious project file with a specially crafted ghidra:// URL. When a user opens this file through File → Open Project, the application deserializes untrusted objects using a Jython 2.7.4 gadget chain, enabling unauthenticated remote code execution. This vulnerability does not require prior authentication and has a CVSS 4.0 score of 8.6, indicating high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary code on the victim's system without authentication. This compromises system confidentiality, integrity, and availability. The attack vector requires user interaction to open a malicious project file, but no privileges or prior access are needed.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should avoid opening untrusted project files, especially those received from unverified sources. Monitor official National Security Agency (NSA) Ghidra advisories for updates regarding patches or mitigations.
