In 1.1.5 and earlier, wireshark-mcp exposes a wireshark_export_objects MCP tool that accepts an attacker-controlled dest_dir parameter and passes it to tshark's --export-objects flag with no mandatory path restriction. The path sandbox (_allowed_dirs) is None by default and only activates when the environment variable WIRESHARK_MCP_ALLOWED_DIRS is explicitly set. In a default installation, any directory on the filesystem can be used as the export destination."}], "lastModified": "2026-05-13T16:16:52.987", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:bx33661:wireshark_mcp:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "C22F6C9B-ECFE-4450-93A4-C1047D82CD27", "versionEndIncluding": "1.1.5"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
