{"id":"BIT-parse-2026-57480","summary":"Parse Server: Denial of service via exponential-time processing of deeply nested query operators","details":"Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.9.1 and 8.6.82, deeply nested $or, $and, and $nor query condition operators in the REST API or LiveQuery query handling could trigger exponential-time processing in the internal query-traversal helper and block the Node.js event loop.
