If a user ran crytic-compile on an address with malicious artifacts verified on etherscan, it was possible to write files on the user's machine by using a relative path e.g.
../../../../.envto traverse above the export directory (crytic-export/). This fix prevents path traversal by ensuring the absolute path of all files written to disk have a common prefix with the export directory.Thank you Lucas Ma (https://twitter.com/MaLucasBC) for responsibly disclosing this vulnerability.
