Starting in version 3.0.0 and prior to version 3.3.1, Dasel\u0027s YAML reader allows an attacker who can supply YAML for processing to trigger extreme CPU and memory consumption. The issue is in the library\u0027s own `UnmarshalYAML` implementation, which manually resolves alias nodes by recursively following `yaml.Node.Alias` pointers without any expansion budget, bypassing go-yaml v4\u0027s built-in alias expansion limit. Version 3.3.2 contains a patch for the issue."
