GHSA-75qh-gg76-p2w4: CWA-2023-004: Excessive number of function parameters in compiled Wasm
(updated )
A specifically crafted Wasm file can cause the VM to consume excessive amounts of memory when compiling a contract. This can lead to high memory usage, slowdowns, potentially a crash and can poison a lock in the VM, preventing any further interaction with contracts.
For more information, see CWA-2023-004.
