CVE-2026-52752 Nsa CVE debrief

CVE-2026-52752 is a path traversal vulnerability in Ghidra, a software reverse engineering (SRE) framework developed by the National Security Agency (NSA). The vulnerability exists in the extension installer and occurs when it fails to properly validate ZIP entry names during extraction. This allows attackers to craft malicious extensions with traversal sequences (e.g., ../ in filenames) to write arbitrary files outside the intended directory. Successful exploitation enables code execution, posing a significant risk to affected systems.
