EPSS 0.07%Parse Server: SQL injection via dot-notation field name in PostgreSQL
描述
### Impact An attacker can use a dot-notation field name in combination with the `sort` query parameter to inject SQL into the PostgreSQL database through an improper escaping of sub-field values in dot-notation queries. The vulnerability may also affect queries that use dot-notation field names with the `distinct` and `where` query parameters. This vulnerability only affects deployments using a PostgreSQL database. ### Patches The fix escapes characters in dot-notation sub-field values that could allow a SQL breakout. ### Workarounds There is no known workaround. ### References - GitHub security advisory: https://github.com/parse-community/parse-server/security/advisories/GHSA-qpr4-jrj4-6f27 - Fix Parse Server 9: https://github.com/parse-community/parse-server/releases/tag/9.6.0-alpha.2 - Fix Parse Server 8: https://github.com/parse-community/parse-server/releases/tag/8.6.28
