CVE-2026-57480: CWE-407: Inefficient Algorithmic Complexity in parse-community parse-server
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 $nor query condition operators in the REST API or LiveQuery query handling could trigger exponential-time processing in the internal query-traversal helper and block the Node.js event loop. This issue is fixed in versions 9.9.1-alpha.12 and 8.6.82.
AI Analysis
Technical Summary
CVE-2026-57480 describes an inefficient algorithmic complexity vulnerability (CWE-407) in parse-community's parse-server. Specifically, deeply nested logical query operators ($or, $and, $nor) in REST API or LiveQuery queries cause exponential-time processing in the internal query-traversal helper. This results in blocking the Node.js event loop, effectively causing a denial of service. The vulnerability affects versions prior to 8.6.82 and the alpha version 9.9.1-alpha.12. The issue is resolved in versions 8.6.82 and 9.9.1-alpha.12.
Potential Impact
Exploitation of this vulnerability can cause the Node.js event loop to be blocked due to exponential-time processing of certain deeply nested queries. This leads to denial of service conditions, potentially making the parse-server unresponsive to legitimate requests. There are no known exploits in the wild at this time.
Mitigation Recommendations
A fix is available in parse-server versions 8.6.82 and 9.9.1-alpha.12. Users should upgrade to these versions or later to remediate this vulnerability. No additional vendor advisory or official patch details are provided, so users should verify the upgrade from official sources.
