cakephp/debug_kit
source listedECOSYSTEM: introduced 0; fixed 4.10.3
### Impact The `MailPreview` feature of debugkit is vulnerable to arbitrary constructor execution. For an application to be vulnerable the following conditions must be true: 1. `debug` mode must be enabled. 2. The hostname must match a 'local' domain or be in an allowlist. ### Patches 5.2.4 and 4.10.3 contain patches for this issue. ### Workarounds Ensure that debugkit is only part of your development dependencies, and that debug mode is disabled in production environments.
