9.8 criticalCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVE-2022-41879
Critical (9.8) in parseplatform parse-server. EPSS 0.9% chance of exploitation in the next 30 days. Fixed in parse-server 4.10.20, 5.3.3.
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. In versions prior to 5.3.3 or 4.10.20, a compromised Parse Server Cloud Code Webhook target endpoint allows an attacker to use prototype pollution to bypass the Parse Server `requestKeywordDenylist` option. This issue has been patched in versions 5.3.3 and 4.10.20. There are no known workarounds.
