Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
OpenRefine's database extension (Maven org.openrefine:database) is vulnerable in versions before 3.7.8. An attacker who can get a user to connect OpenRefine to a malicious MySQL server can exploit a JDBC connection-string flaw, a bypass of the earlier fix for CVE-2023-41887, to read sensitive files on the target server. Upgrade to version 3.7.8.
