SCA: security update for vyper (GHSA-4w26-8p97-f4jp)

low Tenable Cloud Security Plugin ID 420946

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - vyper is a Pythonic Smart Contract Language for the EVM. Vyper handles AugAssign statements by first
 caching the target location to avoid double evaluation. However, in the case when target is an access to a
 DynArray and the rhs modifies the array, the cached target will evaluate first, and the bounds check will
 not be re-evaluated during the write portion of the statement. This issue has been addressed in version
 0.4.1 and all users are advised to upgrade. There are no known workarounds for this vulnerability.
 (CVE-2025-27105)
