Cursor is a code editor built for programming with AI. In versions below 1.3, an attacker can bypass the allow list in auto-run mode with a backtick (`) or $(cmd). If a user has swapped Cursor from its default settings (requiring approval for every terminal call) to an allowlist, an attacker can execute arbitrary command execution outside of the allowlist without user approval. An attacker can trigger this vulnerability if chained with indirect prompt injection. This is fixed in version 1.3.
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.

Command injection vulnerabilities typically occur when:
Many protocols and products have their own custom command language. While OS or shell command strings are frequently discovered and targeted, developers may not realize that these other command languages might also be vulnerable to attacks. Command injection is a common problem with wrapper programs.
