In short
Parse Server can crash when it receives certain malformed file requests. This causes the server to stop working, which is especially critical if you run only one instance without backup.
Technical detail
The vulnerability exists in file request handling due to improper error management (CWE-252, CWE-706), allowing unauthenticated remote attackers to send specially crafted file requests that trigger unhandled exceptions and crash the Node.js process. Availability impact is directly proportional to deployment redundancy; single-instance deployments face complete service disruption.
Summary generated and translated by AI from the official description.
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. In affected versions certain types of invalid files requests are not handled properly and can crash the server. If you are running multiple Parse Server instances in a cluster, the availability impact may be low; if you are running Parse Server as single instance without redundancy, the availability impact may be high. This issue has been addressed in versions 4.10.12 and 5.2.3. Users are advised to upgrade. There are no known workarounds for this issue.
