CVE-2026-96419Public exploitHinoki check available

Code execution via profile ZIP path traversal

Published Sep 29, 2026 · Updated Sep 29, 2026

Path traversal in Wireshark 4.4.0 through 4.4.18 and 4.6.0 through 4.6.8 allows attackers to write outside a profile directory via ZIP import. WiresharkZipHelper::unzip() omits its path-containment check on Windows and accepts relative traversal entries in a crafted configuration-profile ZIP. A user must import the profile; the application can crash, and a file written into the Lua plugin directory can execute on the next launch.
