From 10.6.1 until 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, the #mysql50# bypass prefix is affected because it allows the #mysql50# prefix to bypass normal table-name filesystem encoding. An attacker can trigger the issue with a table name using the #mysql50# prefix, then use a #mysql50# table name to access files under their legacy unencoded name and cause crashes, data corruption, data exfiltration, or remote code execution. This issue is fixed in versions 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2.","published_at":"2026-10-16T16:25:46.964000Z","last_modified_at":"2026-10-21T03:17:20.003000Z","cvss_v3_score":9.9,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","cvss_v3_severity":"CRITICAL","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-706"],"nvd_references":["https://github.com/MariaDB/server/security/advisories/GHSA-65jj-h265-3m7h","https://github.com/MariaDB/server/commit/574ba66b2d6c5d71db83d416677876e9b592858e","https://github.com/MariaDB/server/commit/f277eefa424850a8cba5c2371406047f6395e8bb","https://github.com/MariaDB/server/releases/tag/mariadb-10.11.19","https://github.com/MariaDB/server/releases/tag/mariadb-10.6.28","https://github.com/MariaDB/server/releases/tag/mariadb-11.4.13","https://github.com/MariaDB/server/releases/tag/mariadb-11.8.9","https://github.com/MariaDB/server/releases/tag/mariadb-12.3.3","https://github.com/MariaDB/server/releases/tag/mariadb-13.0.2","https://jira.mariadb.org/browse/MDEV-40362"],"vuln_status":"Analyzed","trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-10-16T21:02:21.118890Z","updated_at":"2026-10-25T14:36:27.259323Z"},"effective_severity":"CRITICAL","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack
