CVE-2026-33539Public exploitNetwork attack vector

SQL injection via unvalidated query field names

Published Mar 24, 2026 · Updated Mar 24, 2026

SQL injection in Parse Server before 8.6.59 and 9.0.0 through 9.6.0-alpha.52 allows remote authenticated users to execute PostgreSQL statements. The PostgreSQL storage adapter passes aggregate $group field references and distinct dot-notation segments into raw SQL interpolation without first rejecting SQL metacharacters. Exploitation requires the Parse master key and a PostgreSQL-backed deployment, granting database-level access beyond Parse Server administration; MongoDB deployments are unaffected.
