Technical description

MariaDB server is a community developed fork of MySQL server. From 10.6.1 until 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, and 13.0.2, SHOW CREATE SERVER, SHOW CREATE USER, and mariadb-dump are affected because each does not consistently quote identifiers and values when serializing SQL. A low-privileged attacker can trigger the issue when an attacker-created object with crafted identifiers or values is included in SHOW output or a dump, then create an object with crafted identifiers or values so generated SQL contains injected statements and execute attacker-injected SQL when the poisoned output is applied. 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.

——0Trigger.dev before 4.5.6 contains an SQL injection vulnerability in the /realtime/v1/runs endpoint, which concatenates the unescaped tags query parameter into the ElectricSQL shape where clause and defeats the runtimeEnvironmentId tenant guard. Authenticated attackers holding any project API key with read:runs scope can append boolean conditions to stream TaskRun records, including payloads and metadata, from every organization on the same self-hosted instance.18h CVE-2026-1140817.7 HIG

——0Trigger.dev before 4.5.6 contains an SQL injection vulnerability in the TSQL query compiler, which concatenates window-function names into generated ClickHouse SQL without allowlisting or escaping. Authenticated customers can submit a backtick-quoted identifier to POST /api/v1/query that injects a raw subquery outside the per-tenant WHERE guard, exfiltrating other organizations' analytics data.18h CVE-2026-1140656.5 MED

—

——0Trigger.dev before 4.7.3 contains a tenant filtering bypass vulnerability that allows authenticated users to read other tenants' data by using placeholder table syntax in POST /api/v1/query. Attackers can submit queries with FROM {database.table} expressions, including within subqueries, to skip table allowlist and tenant filters and expose run metadata and payloads.18h CVE-2026-1137406.3 MED
