CVE-2023-46119Network attack vector

Service crash via undefined extension handling

Published Oct 25, 2023 · Updated Sep 10, 2024

Denial of service in Parse Platform Parse Server 1.0.0 through 5.5.5 and 6.0.0 through 6.3.0 allows remote attackers to crash the server. FilesRouter derives no extension from an extensionless upload, then calls split on the undefined value instead of skipping extension validation. Reachability requires an exposed file-upload route; a successful request terminates the server process and interrupts its API service.
