Quick assessment
Affected
nationalsecurityagency ghidra
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
National Security Agency Ghidra是美国国家安全局（National Security Agency）的一款软件逆向工程（SRE）框架。 National Security Agency Ghidra 12.1之前版本存在路径遍历漏洞，该漏洞源于SameDirDebugInfoProvider在从ELF二进制.gnu_debuglink部分构建文件路径前未验证文件名，攻击者可制作包含遍历序列的恶意ELF二进制文件，在自动DWARF分析期间探测文件系统存在性并泄露任意文件的CRC

Vulnerability Title
Ghidra < 12.1 - Path Traversal via .gnu_debuglink in DWARF External Debug File Resolution
Source: CVE Program / CVE List V5
Vulnerability Description
Ghidra before 12.1 contains a path traversal vulnerability in SameDirDebugInfoProvider that fails to validate filenames from ELF binary .gnu_debuglink sections before constructing file paths. Attackers can craft malicious ELF binaries with traversal sequences to probe filesystem existence and leak CRC32 hashes of arbitrary files during automatic DWARF analysis.
