CVE-2026-49495 Details
Description
Ghidra 10.2 before 12.1 contains an uncontrolled resource consumption vulnerability in ExportTrie.parseTrie() that lacks cycle detection when traversing Mach-O binary export tries. A crafted Mach-O binary with circular references in the export trie causes unbounded queue growth and exponential string concatenation, triggering OutOfMemoryError that crashes the entire JVM and loses all unsaved work.
A denial-of-service vulnerability has been identified in Ghidra versions 10.2 prior to 12.1. The issue arises in the ExportTrie.parseTrie() method, which processes Mach-O binary export tries without proper cycle detection. This flaw allows a specially crafted Mach-O binary containing circular references in the export trie to cause unbounded queue growth and exponential string concatenation. The resulting OutOfMemoryError crashes the Java Virtual Machine, leading to the loss of all unsaved work in Ghidra.
Users are advised to upgrade to Ghidra version 12.1 or later, which includes the necessary fix for this vulnerability.
