Title
WPGraphQL Smart Cache before 2.3.3 Unbounded Persisted Query Storage DoS
Summary
WPGraphQL Smart Cache before 2.3.3 contains an uncontrolled resource consumption vulnerability that allows unauthenticated attackers to persist unlimited query documents via the Automatic Persisted Query handler. Attackers can send distinct queries with matching SHA-256 queryId values, including batched operations, to grow the wp_posts table without bound and degrade database performance.
