DescriptionA flaw was found in the AAP MCP server. An unauthenticated remote attacker can exploit a log injection vulnerability by sending specially crafted input to the `toolsetroute` parameter. This parameter is not properly sanitized before being written to logs, allowing the attacker to inject control characters such as newlines and ANSI escape sequences. This enables the attacker to obscure legitimate log entries and insert forged ones, which could facilitate social engineering attacks, potentially leading to an operator executing dangerous commands or visiting malicious URLs.
