Policy evaluation mixed server-derived identity and transport values with raw headers and query parameters. A client could therefore shadow internal condition keys, synthesize LDAP or JWT resource variables, substitute request tags for stored tags, or make a condition observe a value different from the one the handler actually used.
Partition condition sources, reserve internal names, adopt exact-name lookup from silo-pkg, and bind authorization to the effective request state. Preserve compatible query forms for storage class and upload tags with explicit header precedence, while restricting signature age and existing-object tags to authenticated or server-resolved values.
Tests sweep every supported key across header and query routes and exercise LDAP/OIDC variables, object-lock spelling, STS tags, metadata extraction, and end-to-end policy decisions.

Following policies if present
```
"Condition": {
"IpAddress": {
"aws:SourceIp": [
"54.240.143.0/24",
"2001:DB8:1234:5678::/64"
]
}
}
```
And client is making a request to MinIO via IPv6 can
potentially crash the server.
Workarounds are turn-off IPv6 and use only IPv4
This is to ensure that there are no projects
that try to import `minio/minio/pkg` into
their own repo. Any such common packages should
go to `https://github.com/minio/pkg`
