High impact if exploited, but EPSS currently rates exploitation as unlikely (2.11%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Command injection vulnerability in console.run_module_with_output() in pymetasploit3 through version 1.0.6 allows attackers to inject newline characters into module options such as RHOSTS. This breaks the intended command structure and causes the Metasploit console to execute additional unintended commands, potentially leading to arbitrary command execution and manipulation of Metasploit sessions.
