CVE-2021-39187

7.5 highEPSS 1.8%

High (7.5) in parseplatform parse-server. EPSS 1.8% chance of exploitation in the next 30 days. Fixed in parse-server 4.10.3.

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to version 4.10.3, Parse Server crashes when if a query request contains an invalid value for the `explain` option. This is due to a bug in the MongoDB Node.js driver which throws an exception that Parse Server cannot catch. There is a patch for this issue in version 4.10.3. No workarounds aside from upgrading are known to exist.
