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.\n\n### Patches\nEPyT-Flow has been patched in 0.16.1 -- affects all versions <= 0.16.0\n\n### Workarounds\nDo not load any JSON from untrusted sources and do not expose the REST API.\n\n### Credits\nEPyT-Flow thanks Jarrett Chan (@syphonetic) for detecting and reporting the bug.","affected":[{"package":{"name":"epyt-flow","ecosystem":"PyPI","purl":"pkg:pypi/epyt-flow"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.16.1"}]}],"versions":["0.1.0","0.1.1","0.10.0","0.11.0","0.12.0","0.13.0","0.13.1","0.14.0","0.14.1","0.14.2","0.15.0","0.15.0b1","0.16.0","0.2.0","0.3.0","0.4.0","0.5.0","0.6.0","0.7.0","0.7.1","0.7.2","0.7.3","0.8.0","0.8.1","0.9.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/02/GHSA-74vm-8frp-7w68/GHSA-74vm-8frp-7w68.json"}}],"references":[{"type":"WEB","url":"https://github.com/WaterFutures/EPyT-Flow/security/advisories/GHSA-74vm-8frp-7w68"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25632"},{"type":"WEB","url":"https://github.com/WaterFutures/EPyT-Flow/commit/3fff9151494c7dbc72073830b734f0a7e550e385"},{"type":"PACKAGE","url":"https://github.com/WaterFutures/EPyT-Flow"},{"type":"WEB","url":"https://github.com/WaterFutures/EPyT-Flow/releases/tag/v0.16.1"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/epyt-flow/PYSEC-2026-330.yaml"},{"type":"WEB","url":"https://pypi.org/project/epyt-flow"}],"database_specific":{"cwe_ids":["CWE-502"],"github_reviewed":true,"github_reviewed_at":"2026-02-04T20:34:28Z","nvd_published_at":"2026-02-06T21:16:18Z","severity":"CRITICAL"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H"}]} |
