## [5.4.1](https://github.com/parse-community/parse-server/compare/5.4.0...5.4.1) (2023-01-31) ### Bug Fixes * The client IP address may be determined incorrectly in some cases; it is now required to set the Parse Server option `trustProxy` accordingly if Parse Server runs behind a proxy server, see the express framework's [trust proxy](https://expressjs.com/en/guide/behind-proxies.html) setting; this fixes a security vulnerability in which the Parse Server option `masterKeyIps` may be circumvented, see [GHSA-vm5r-c87r-pf6x](https://github.com/parse-community/parse-server/security/advisories/GHSA-vm5r-c87r-pf6x) ([#8369](https://github.com/parse-community/parse-server/issues/8369)) ([e016d81](e016d813e0))
