Description

### Impact 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. ### Patches The fix escapes single quotes in the sub-key name before interpolating it into the SQL query, preventing breakout from SQL string literals. ### Workarounds There is no known workaround. ### References - GitHub security advisory: https://github.com/parse-community/parse-server/security/advisories/GHSA-gqpp-xgvh-9h7h - Fix Parse Server 9: https://github.com/parse-community/parse-server/releases/tag/9.6.0-alpha.5 - Fix Parse Server 8: https://github.com/parse-community/parse-server/releases/tag/8.6.31
