Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Magistrala before 1.0.0 contains a SQL injection vulnerability in the timescale-reader and postgres-reader HTTP API services that allows authenticated attackers to inject arbitrary SQL by supplying a malicious format query parameter that is interpolated directly into the FROM clause without parameterization or identifier quoting. Attackers with a self-registered account can substitute arbitrary subqueries to achieve cross-tenant database reads, extract pg_shadow password hashes, read and write arbitrary files, and execute arbitrary code as the postgres OS user by loading attacker-supplied shared objects, with all injected SQL executing at superuser privilege due to the default PostgreSQL role configuration.
