CVE-2026-49497: Ghidra < 12.1 - Path Traversal via .gnu_debuglink in DWARF External Debug File Resolution

MediumCVSS 4.6 · v4.0—No exploit No fix recorded

Noroxi assessment

Priority: Monitor (action score 18/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.18% (FIRST EPSS).
Someone with local access to the system can trigger it. No account or password is required. No special conditions are required; it is repeatable.
According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

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.

Root cause

A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.

The bug in code

The whole CWE-22 class

A representative example of this vulnerability class. Not the vendor's source code; it shows the faulty pattern and its fix.

Vulnerable

Fixed

1const file = path.resolve(ROOT, req.query.name);
