{"id":"DEBIAN-CVE-2026-49261","details":"MariaDB server is a community developed fork of MySQL server. Versions 10.6.1 through 10.6.26, 10.11.1 through 10.11.17, 11.4.1 through 11.4.11, 11.8.1 through 11.8.7, and 12.3.1 with  `wsrep_notify_cmd` enabled would execute shell commands embedded in the name of the joiner node. This is fixed in 10.6.27, 10.11.18, 11.4.12, 11.8.8, and 12.3.2. As a workaround, anyone who cannot upgrade now should disable `wsrep_notify_cmd`.","modified":"2026-08-27T23:06:27.013978320Z","published":"2026-06-11T18:16:26.553Z","upstream":["CVE-2026-49261"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-49261"}],"affected":[{"package":{"name":"mariadb","ecosystem":"Debian:12","purl":"pkg:deb/debian/mariadb?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:10.11.18-0+deb12u1"}]}],"versions":["1:10.11.11-0+deb12u1","1:10.11.13-0+deb12u1","1:10.11.14-0+deb12u1","1:10.11.14-0+deb12u2","1:10.11.3-1","1:10.11.3-2~exp1","1:10.11.4-1","1:10.11.4-1~deb12u1","1:10.11.5-1","1:10.11.5-2","1:10.11.5-3","1:10.11.6-0+deb12u1","1:10.11.6-1","1:10.11.6-2","1:10.11.6-2.1~exp1","1:10.11.7-1","1:10.11.7-2","1:10.11.7-3","1:10.11.7-4","1:10.11.8-1","1:10.11.9-0+deb12u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-49261.json"}},{"package":{"name":"mariadb","ecosystem":"Debian:13","purl":"pkg:deb/debian/mariadb?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:11.8.2-1","1:11.8.3-0+deb13u1","1:11.8.3-1","1:11.8.5-1","1:11.8.5-2","1:11.8.5-3","1:11.8.5-3~exp1","1:11.8.5-3~exp2","1:11.8.5-3~exp3","1:11.8.5-4","1:11.8.6-0+deb13u1","1:11.8.6-1","1:11.8.6-2","1:11.8.6-3","1:11.8.6-4","1:11.8.6-5","1:11.8.6-6","1:11.8.8-0+deb13u1","1:11.8.8-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-49261.json"}},{"package":{"name":"mariadb","ecosystem":"Debian:14","purl":"pkg:deb/debian/mariadb?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:11.8.8-1"}]}],"versions":["1:11.8.2-1","1:11.8.3-1","1:11.8.5-1","1:11.8.5-2","1:11.8.5-3","1:11.8.5-3~exp1","1:11.8.5-3~exp2","1:11.8.5-3~exp3","1:11.8.5-4","1:11.8.6-1","1:11.8.6-2","1:11.8.6-3","1:11.8.6-4","1:11.8.6-5","1:11.8.6-6"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-49261.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
