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 MariaDB view FRM parser did not safely encode embedded newline characters in a username. An account with CREATE USER and CREATE VIEW WITH GRANT OPTION could create a crafted username containing additional view metadata, causing the parser to interpret part of the username as security metadata and potentially escalating database privileges. 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.\n\n## Affected\n\n- `mariadb >= 10.6.1, < 10.6.28`\n- `mariadb >= 10.11.1, < 10.11.19`\n- `mariadb >= 11.4.1, < 11.4.13`\n- `mariadb >= 11.8.1, < 11.8.9`\n- `mariadb >= 12.3.1, < 12.3.3`\n- `mariadb >= 13.0.1, < 13.0.2`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `mariadb 13.0.2`\n\n## Vendor advisories\n\n- **Red Hat VEX** · Important · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat Hardened Images, Red Hat OpenStack Platform 13 (Queens) · no fix planned: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, … · updated 2026-10-19 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-107823.json)\n- **RHSA-2026:84701** · Red Hat · fixed in: Red Hat Hardened Images · released 2026-10-19 · [advisory](https://access.redhat.com/errata/RHSA-2026:84701)\n- **RHSA-2026:83108** · Red Hat · fixed in: Red Hat Hardened Images · released 2026-10-14 · [advisory](https://access.redhat.com/errata/RHSA-2026:83108)","depth":"twilight","depthScore":40,"depthScoreParts":{"impact":39.6,"likelihood":0.2,"exploitation":0,"ransomware":0},"changes":[]}
