CVE-2026-49495: Nsa Ghidra

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Nsa Ghidra: from 10.2, before 12.1 (fixed in 12.1)
