Technical details
A path traversal vulnerability (CWE-22) exists in Cursor versions prior to 3.0. The application's AI agent runs terminal commands within a sandbox that automatically grants write access to the command's working directory. However, the agent could manipulate the 'working_directory' parameter to point to sensitive locations outside the intended workspace. An attacker could exploit this to overwrite critical system or application files, such as the 'cursorsandbox' helper, leading to full escape from the sandbox and non-sandboxed Remote Code Execution (RCE) under the privileges of the local user. This issue is resolved in version 3.0 by removing write access based on agent-controlled directory parameters.
