CNA source text (English)
Vyper 0.2.13 before 0.2.15 Storage Corruption via @nonreentrant Decorator
Vyper from 0.2.13 before 0.2.15 allocates storage slots for @nonreentrant reentrancy locks at the same locations as contract storage variables. When a function using @nonreentrant is called, setting the lock overwrites the overlapping storage variable, corrupting contract state and breaking the contract's intended logic.
