CVE-2026-49495 is a medium-severity vulnerability rated 6.7/10 on the CVSS scale. 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.. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
