Host file disclosure via JDBC option injection
Published Feb 12, 2024 · Updated May 7, 2025
Path traversal in OpenRefine 3.7.7 and earlier allows remote attackers to read host files through a crafted MySQL JDBC connection. MySQLConnectionManager builds a JDBC URL by concatenating the Host field without rejecting parenthesized key-value settings, enabling local-infile options. The local web server must be reachable, after which a malicious MySQL server can obtain files readable by the OpenRefine process.
