CVE-2026-49497

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.

Summary		(es) Ghidra antes de 12.1 contiene una vulnerabilidad de salto de ruta en SameDirDebugInfoProvider que no valida los nombres de archivo de las secciones .gnu_debuglink de binarios ELF antes de construir rutas de archivo. Los atacantes pueden crear binarios ELF maliciosos con secuencias de salto para sondear la existencia del sistema de archivos y filtrar hashes CRC32 de archivos arbitrarios durante el análisis DWARF automático.
