CVE-2026-57480 Parse Server: Denial of service via exponential-time processing of deeply nested query operators

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.9.1-alpha.12 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...

SurrealDB: Authorization Bypass in KILL Statement Allows Termination of Other Users' Live Queries

The KILL statement is used to terminate LIVE SELECT subscriptions that capture real-time changes to data within a table. The KILL statement implementation in core/src/expr/statements/kill.rs verifies that the requesting user has database-level access, but does not verify that the requesting user ...
