Prior to 0.1.8, netlicensing_get_product passes the caller-controlled product_number to src\/netlicensing_mcp\/tools\/products.py, which interpolates it into a REST path consumed by nl_get() in src\/netlicensing_mcp\/client.py without path-segment validation. A traversal segment can be normalized from the intended product path to the \/token endpoint, after which the response is serialized through _wrap_json instead of _wrap_json_token_read, bypassing redact_token_read() protections for APIKEY number and SHOP shopURL fields. An authenticated MCP client with a non-administrative API key can retrieve plaintext token values, and a recovered administrative token can provide broad read, write, and delete access to the NetLicensing account.
