Vyper's sqrt doesn't define rounding behavior

Vyper's sqrt builtin uses the babylonian method to calculate square roots of decimals. Unfortunately, improper handling of the oscillating final states may lead to sqrt incorrectly returning rounded up results. the fix is tracked in https://github.com/vyperlang/vyper/pull/4486 Vulnerability Detai...

CVE-2025-26622

The CVE concerns vyper’s sqrt() builtin, which uses the Babylonian method for decimals. The problem arises from improper handling of oscillating final states, which can cause sqrt to return a rounded-up value (e.g., for certain inputs, 0.9999999998 → 0.9999999999). The issue is detailed in the GH...
