{“lastseen”:””,”description”:”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\u2019s 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. This allows invoking dangerous classes such as subprocess.Popen, which can lead to OS command execution during JSON parsing. This also affects the loading of JSON files. This vulnerability is fixed in 0.16.1.”,”published”:”2026-02-06T20:24:18.213Z”,”modified”:”2026-02-06T20:56:43.719Z”,”type”:”cve”,”title”:”EPyT-Flow has unsafe JSON deserialization (__type__)”,”source”:”GitHub_M”,”references”:”https:\/\/github.com\/WaterFutures\/EPyT-Flow\/security\/advisories\/GHSA-74vm-8frp-7w68\\nhttps:\/\/github.com\/WaterFutures\/EPyT-Flow\/commit\/3fff9151494c7dbc72073830b734f0a7e550e385\\nhttps:\/\/github.com\/WaterFutures\/EPyT-Flow\/releases\/tag\/v0.16.1″,”id”:”CVE-2026-25632″,”bulletinFamily”:””,”cwe”:[“CWE-502″],”cvelist”:null,”sourceData”:”WaterFutures EPyT-Flow \\u003c 0.16.1″,”sourceHref”:””,”cvss”:{“score”:10,”severity”:”CRITICAL”,”vector”:”CVSS:3.1\/AV:N\/AC:L\/PR:N\/UI:N\/S:C\/C:H\/I:H\/A:H”,”version”:”3.1″},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:””,”category_name”:”CVE”,”post_link”:””,”product”:”EPyT-Flow”,”version”:”\\u003c 0.16.1″,”vendor”:”WaterFutures”,”ai_description”:”EPyT-Flow has an unsafe JSON deserialization vulnerability, allowing OS command execution during JSON parsing”,”ai_severity”:”Critical”,”ai_vendor”:”WaterFutures”,”ai_product”:”EPyT-Flow”,”ai_version”:”\\u003c 0.16.1″,”ai_score”:10}<\/p>\n","protected":false},"excerpt":{"rendered":"
