Technical details
The vulnerability is an authorization bypass in the http_request tool within Strands Agents Tools.

An authenticated agent or user with network connectivity to the http_request tool can exploit this flaw to access restricted resources or perform unauthorized operations. The vulnerability does not require special preconditions beyond basic agent execution access. No patch information is available in the advisory.
