CVE-2026-25632 is a critical-severity flaw (CVSS 10.0) affecting epyt-flow. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
EPyT-Flow is a Python package designed for the easy generation of hydraulic and water quality scenario data of water distribution networks. Prior to 0.16.1, EPyT-Flow’s REST API parses attacker-controlled JSON request bodies using a custom deserializer (my_load_from_json) that supports a type field. When type is present, the deserializer dynamically imports an attacker-specified module/class and instantiates it with attacker-supplied arguments. T
