Overview

CVE-2026-4946 is a high-severity vulnerability. It was published on March 29, 2026 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
