GHSA-QHR6-MGQR-MCHM Vyper's `concat()` builtin may elide side-effects for zero-length arguments

Impact concat may skip evaluation of side effects when the length of an argument is zero. this is due to a fastpath in the implementation which skips evaluation of argument expressions when their length is zero:...

CVE-2025-47285

Vyper is the Pythonic Programming Language for the Ethereum Virtual Machine. In versions up to and including 0.4.2rc1, concat may skip evaluation of side effects when the length of an argument is zero. This is due to a fastpath in the implementation which skips evaluation of argument expressions...

CVE-2025-47774

Vyper is the Pythonic Programming Language for the Ethereum Virtual Machine. In versions up to and including 0.4.2rc1, the slice builtin can elide side effects when the output length is 0, and the source bytestring is a builtin msg.data or .code. The reason is that for these source locations, the...
