Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
OpenRefine versions before 3.8.3 have a path traversal flaw in the load-language command, which builds a localization file path from a user-supplied lang parameter without checking that the resulting path stays within the expected directory. An attacker who can reach this command may be able to read other JSON files on the server's file system. Upgrade to OpenRefine 3.8.3 or later. The source gives few details on the attacker's required access.
