CVE-2026-14537
CRITICALAn unauthenticated attacker can invoke protected tools via legacy HTTP endpoints in Google's mcp-toolbox v1.3.0 and v1.4.0 when the --enable-api flag is active.
This authorization bypass allows remote code execution through tool invocation, directly impacting DIB compliance by enabling unauthenticated access to protected scopes. Organizations must patch immediately and disable the --enable-api flag to prevent exploitation.
Shame score — A critical authorization flaw allowing unauthenticated tool invocation demonstrates severe negligence in access control design and exposes systems to arbitrary code execution.
▸ RECOMMENDED ACTION Remote code execution — patch the affected products on priority.
Incorrect Authorization in the direct HTTP API tool invocation endpoint in Google mcp-toolbox versions v1.3.0 and v1.4.0 allows an unauthenticated attacker to invoke tools protected by the scopeRequired feature via sending tool invocation requests through legacy HTTP endpoints when the --enable-api flag is active.
