We will also cherrypick this commit on TensorFlow 2.11.1.\n\n\n### For more information\nPlease consult [our security guide](https://github.com/tensorflow/tensorflow/blob/master/SECURITY.md) for more information regarding the security model and how to contact us with issues and questions.\n\n\n### Attribution\nThis vulnerability has been reported by r3pwnx of 360 AIVul Team\n","published":"2023-03-24T23:10:30.431Z","modified":"2026-08-12T13:33:58.761986Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"tensorflow","fixedVersion":"2.11.1"},{"ecosystem":"PyPI","name":"tensorflow-cpu","fixedVersion":"2.11.1"},{"ecosystem":"PyPI","name":"tensorflow-gpu","fixedVersion":"2.11.1"}],"fix":{"url":"https://github.com/tensorflow/tensorflow/commit/da66bc6d5ff466aee084f9e7397980a24890cd15","label":"tensorflow/tensorflow@da66bc6"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/25xxx/CVE-2023-25676.json"},{"type":"ADVISORY","url":"https://github.com/tensorflow/tensorflow/security/advisories/GHSA-6wfh-89q8-44jq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-25676"},{"type":"FIX","url":"https://github.com/tensorflow/tensorflow/commit/da66bc6d5ff466aee084f9e7397980a24890cd15"},{"type":"PACKAGE","url":"https://github.com/tensorflow/tensorflow"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T13:33:58.761986Z"}}
