The issue occurs because the `status` argument during validation failures is not properly checked. Since each of the above methods can return an error status, the `status` value must be checked before continuing. The issue is patched in commit 22e07fb204386768e5bcbea563641ea11f96ceb8 and is released in TensorFlow versions 2.2.1, or 2.3.1.","published":"2020-09-25T19:15:14.480Z","modified":"2026-08-07T15:11:45.794411Z","cvss":{"score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"PyPI","name":"tensorflow","fixedVersion":"2.2.1"},{"ecosystem":"PyPI","name":"tensorflow","fixedVersion":"2.3.1"},{"ecosystem":"PyPI","name":"tensorflow-cpu","fixedVersion":"2.2.1"},{"ecosystem":"PyPI","name":"tensorflow-cpu","fixedVersion":"2.3.1"},{"ecosystem":"PyPI","name":"tensorflow-gpu","fixedVersion":"2.2.1"},{"ecosystem":"PyPI","name":"tensorflow-gpu","fixedVersion":"2.3.1"}],"fix":{"url":"https://github.com/tensorflow/tensorflow/commit/22e07fb204386768e5bcbea563641ea11f96ceb8","label":"tensorflow/tensorflow@22e07fb"},"references":[{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00065.html"},{"type":"ADVISORY","url":"https://github.com/tensorflow/tensorflow/releases/tag/v2.3.1"},{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/commit/22e07fb204386768e5bcbea563641ea11f96ceb8"},{"type":"EVIDENCE","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-8fxw-76px-3rxv"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T15:11:45.794411Z"}}
