CVE-2026-115503
Ghidra before 12.2 contains an improper handling of highly compressed data vulnerability in ExtensionUtils.unzipToInstallationFolder() that allows attackers to exhaust disk space.
Does this matter?
Lower severity and a low EPSS score (0.12%). Track it; it rarely justifies an emergency change on its own.
Description
Ghidra before 12.2 contains an improper handling of highly compressed data vulnerability in ExtensionUtils.unzipToInstallationFolder() that allows attackers to exhaust disk space. Attackers can persuade users to install a crafted zip bomb extension archive that expands without size limits, causing later writes by Ghidra and other applications to fail.
