Prior to 9.6.0-alpha.5 and 8.6.31, a SQL injection vulnerability exists in the PostgreSQL storage adapter when processing Increment operations on nested object fields using dot notation (e.g., stats.counter). The sub-key name is interpolated directly into SQL string literals without escaping. An attacker who can send write requests to the Parse Server REST API can inject arbitrary SQL via a crafted sub-key name containing single quotes, potentially executing commands or reading data from the database, bypassing CLPs and ACLs. Only Postgres deployments are affected. This vulnerability is fixed in 9.6.0-alpha.5 and 8.6.31."}],"source":{"advisory":"GHSA-gqpp-xgvh-9h7h","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-03-12T20:09:48.204957Z","id":"CVE-2026-31871","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-03-12T20:09:53.852Z"}}]}}
