* s3: reject requests carrying more than one routed subresource Routing picks the first matching subresource route while authorization resolves a single action from the query, and the two can disagree. A bucket-level PUT ?tagging&policy is authorized as s3:PutBucketTagging but served by PutBucketPolicyHandler, letting a tagger rewrite the bucket policy; the same shape lets a list grant read the policy via ?list-type=2&policy or ?versions&policy, and lets an object ACL writer retag via PUT ?acl&tagging. Declining ambiguous requests keeps the authorized action and the served handler identical. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * s3: reuse hasAmbiguousSubresource in the routed-subresource guard The standalone key list dropped versioning, so ?versioning&policy still reached route matching and auth with two operations. The bucket-level check already keys off operationSubresources plus bucketQueryActions; running the same predicate keeps the lists from drifting apart. --------- Co-authored-by: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>
