The proposal aims to upgrade Polkadot's runtime to v9281 after an issue was identified on the last release presenting the possibility of adding inherents containing fake data to a block. This release fixes the vulnerabilities and includes:

Runtime

✅ audited #11918 Low - Make new storage layer truly default

✅ trivial #11690 Low - Add event to pallet asset-tx-payment

✅ audited #11796 Low - Auto-incremental collectionid

✅ trivial #11985 Low - Pallet-contracts: fix 16bit func_id

✅ trivial #11991 Low - Contracts: apply depth limit when decoding

⏳ pending non-critical audit #11819 ❗️ Medium - Transaction payment runtime api: query call info and fee details

✅ audited #11927 Low - Transactional: wrap pallet::calls directly in storage layers

✅ trivial #5582 Low - Add nomination pools to polkadot runtime

✅ trivial #5910 Low - Update weights

It also includes the fix to a vulnerability which potentially impacts block authoring. If passed by the Council, this proposal should be voted by the community for final decision and enacted after.
