CVE-2026-49497

Filesystem information disclosure via debuglink path traversal

Published Jun 10, 2026 · Updated Jun 10, 2026

Path traversal in Ghidra before 12.1 allows attackers to disclose local file existence and CRC32 hashes through crafted ELF files. SameDirDebugInfoProvider joins the raw .gnu_debuglink filename to the program directory, tests the resulting path, reads the target to calculate its CRC32 value, and logs that value. The default-enabled DWARF analyzer triggers during ELF import, so exploitation requires an analyst or automated pipeline to process the crafted file.
