Description

A vulnerability chain in Cribl Edge for Windows before 4.17.1 allows a local authenticated user to escalate privileges to NT AUTHORITY\SYSTEM. Incorrect default permissions on the Windows installer's authentication directory (CWE-276) expose a cryptographic secret used for JWT signing and password-hash derivation, enabling forgery of administrative API tokens. The forged token can then be used to invoke a pipeline function that reaches an OS command sink (CWE-78) running in the SYSTEM context.
