CVE-2026-4946: Nsa Ghidra

High severity, CVSS 8.8. EPSS: 0.8% chance of exploitation in the next 30 days.

Ghidra versions prior to 12.0.3 improperly process annotation directives embedded in automatically extracted binary data, resulting in arbitrary command execution when an analyst interacts with the UI. Specifically, the @execute annotation (which is intended for trusted, user-authored comments) is also parsed in comments generated during auto-analysis (such as CFStrings in Mach-O binaries). This allows a crafted binary to present seemingly benign clickable text which, when clicked, executes attacker-controlled commands on the analyst’s machine.

Affected products

• Nsa Ghidra: before 12.0.3 (fixed in 12.0.3)
