Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

MariaDB Connector/J versions 3.0.0 through 3.3.6, 3.4.0 through 3.4.4, and 3.5.0 through 3.5.10 can decode query results as UTF-8 even when the server has switched character_set_results to another charset. An attacker who controls the database server or sits in a man-in-the-middle position on the connection could alter the strings an application reads, which may defeat validation or escaping. Upgrade to 3.3.7, 3.4.5, 3.5.11, or later.
