CVE-2026-55859

MariaDB Connector/R2DBC is a non-blocking MariaDB and MySQL client implemented in Java. Prior to 1.4.1, org.mariadb:r2dbc-mariadb encodes and decodes all character data under the assumption that the connection character set is UTF-8. A server can announce a mid-session change to charactersetclien...

org.mariadb:r2dbc-mariadb has Inappropriate Encoding for Output Context and Improper Encoding or Escaping of Output

Summary The connector encodes and decodes all character data assuming the connection character set is UTF-8. A server can change charactersetclient mid-session to a non-UTF-8 charset, after which the driver and server interpret the same bytes under different encodings, causing silent data...
