Prior to 2.7.14, 3.3.5, 3.4.3, and 3.5.9, the connector encodes and decodes protocol text and performs client-side escaping under the assumption that the connection character set is UTF-8. The server can report a mid-session change to character_set_client through OK-packet session-state tracking, including a change caused by SET NAMES, a stored routine or trigger, server configuration, or a hostile server. If character_set_client changes to a non-UTF-8 value, the driver continues to read and write UTF-8 while the server interprets the same bytes under another encoding, causing silent data corruption and a client/server charset-confusion mismatch that can defeat byte-wise quoting or escaping. The fix accepts only utf8, utf8mb3, or utf8mb4 after initialization; any other value causes SQLException with SQLState 08000 and closes the connection. This issue is fixed in versions 2.7.14, 3.3.5, 3.4.3, and 3.5.9.","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).","title":"Terms of use"}],"publisher":{"category":"vendor","contact_details":"https://www.suse.com/support/security/contact/","name":"SUSE Product Security Team","namespace":"https://www.suse.com/"},"references":[{"category":"external","summary":"CVE-2026-55858","url":"https://www.suse.com/security/cve/CVE-2026-55858"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1278305 for CVE-2026-55858","url":"https://bugzilla.suse.com/1278305"}],"title":"SUSE CVE CVE-2026-55858","tracking":{"current_release_date":"2026-09-03T16:28:31Z","generator":{"date":"2026-09-03T16:28:31Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2026-55858","initial_release_date":"2026-09-03T16:28:31Z","revision_history":[{"date":"2026-09-03T16:28:31Z","number":"2","summary":"references added,severity changed from  to moderate"}],"status":"interim","version":"2"}}}
