The word Remote in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. This means an attacker or victim needs to execute code from the local machine to exploit the vulnerability.
How could an attacker exploit this vulnerability?
Via a malicious Cross Prompt Inject in untrusted files or MCP servers, an attacker could execute additional commands by appending them to commands allowed in the user's terminal auto-approve setting.
