CVE-2026-57496: NetLicensing MCP Server

The National Vulnerability Database (NVD) record says the NetLicensing Model Context Protocol (MCP) Server before 0.1.8 does not check a product-number argument for path segments, so an MCP client holding a non-administrative API key can reach the token endpoint and read plaintext token values, and a recovered administrative token can give read, write and delete access to the NetLicensing account; fixed in 0.1.8.

A signal's controls are the ones its record points at, the exposure; a case's controls are the ones its records show were absent or failed, so the two can differ.

Corrections

Changes to what this signal says, with the reason. Every earlier version is kept.

• 2026-10-22: Summary. Found in an independent read against the record on 22 October 2026: the record says the argument is not checked for path segments, and that it is a recovered administrative token that gives full access (CVE record CVE-2026-57496).
  Show the change

  Before: NVD records that the NetLicensing MCP Server before 0.1.8 does not validate a product-number argument, so an MCP client holding a non-administrative API key can reach the token endpoint and read plaintext token values, which can give read, write and delete access to the NetLicensing account; fixed in 0.1.8.

  After: The National Vulnerability Database (NVD) record says the NetLicensing Model Context Protocol (MCP) Server before 0.1.8 does not check a product-number argument for path segments, so an MCP client holding a non-administrative API key can reach the token endpoint and read plaintext token values, and a recovered administrative token can give read, write and delete access to the NetLicensing account; fixed in 0.1.8.

What a signal is. A signal records what a primary record says; it assigns no fault. It is lighter than a case: one dated item from one record, tagged with the world, sector and controls it touches. It becomes a case when it meets the bar for one.
