Description
Adds a new vulnerability disclosure for ERC-1271 orders.
This used to affect Milkman orders but has been fixed in cowdao-grants/milkman#1 and related infrastructure in cowprotocol/milkman-bot#5.
No "official" contracts are affected by this issue anymore.
Credits
This issue was brought to our attention thanks to the report by Quantura Tech with their analysis of the negative effects on the solver competition when order fees can be manipulated.
