Name of the Vulnerable Software and Affected Versions Parse Server versions prior to 9.9.1-alpha.12 Parse Server versions prior to 8.6.82
Description Deeply nested $or, $and, and $nor query condition operators used in the REST API or LiveQuery query handling can trigger exponential-time processing within the internal query-traversal helper. This behavior blocks the Node.js event loop, which is the single-threaded mechanism that handles all asynchronous operations in Node.js, potentially leading to a denial of service.
Recommendations Update Parse Server to version 9.9.1-alpha.12 or later. Update Parse Server to version 8.6.82 or later.
