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 CONNECT engine's DOS table type used an incorrect boundary check that permitted a one-byte null write beyond a stack buffer at an attacker-controlled offset. An authenticated user able to use the CONNECT engine could cause a crash and potentially 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":"2026-10-09T16:05:49.046000Z","last_modified_at":"2026-10-14T14:12:37.777000Z","cvss_v3_score":8.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","cvss_v3_severity":"HIGH","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-787"],"nvd_references":["https://github.com/MariaDB/server/security/advisories/GHSA-4wgx-ffg9-jrwq","https://github.com/MariaDB/server/commit/b369925f6855d3e1f0ebcf453492724b99fda6f8","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-40637"],"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":"2026-10-09T16:37:29.223859Z","updated_at":"2026-10-16T05:01:51.215417Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack
