{"cve":"CVE-2020-15194","nvd":{"published":"2020-09-25T19:15:14.683","modified":"2026-06-17T02:56:14.320","status":"Modified","description":"In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the `SparseFillEmptyRowsGrad` implementation has incomplete validation of the shapes of its arguments. Although `reverse_index_map_t` and `grad_values_t` are accessed in a similar pattern, only `reverse_index_map_t` is validated to be of proper shape. Hence, malicious users can pass a bad `grad_values_t` to trigger an assertion failure in `vec`, causing denial of service in serving installations. The issue is patched in commit 390611e0d45c5793c7066110af37c8514e6a6c54, and is released in TensorFlow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, or 2.3.1.\"","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3},"cwes":["CWE-617","CWE-20"],"references":["http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00065.html","https://github.com/tensorflow/tensorflow/commit/390611e0d45c5793c7066110af37c8514e6a6c54","https://github.com/tensorflow/tensorflow/releases/tag/v2.3.1","https://github.com/tensorflow/tensorflow/security/advisories/GHSA-9mqp-7v2h-2382","http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00065.html"],"products":["google:tensorflow","opensuse:leap"],"source":"nvd","synced_at":"2026-10-19T21:09:53.489947993+00:00"},"epss":{"cve":"CVE-2020-15194","score":0.01026,"percentile":0.63608,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-9mqp-7v2h-2382","url":"https://osv.dev/vulnerability/GHSA-9mqp-7v2h-2382","summary":"Denial of Service in Tensorflow","modified":"2026-07-08T06:28:25.050512524Z","packages":[{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":["<1.15.4"],"fixed":["1.15.4"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.0.0 <2.0.3"],"fixed":["2.0.3"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.1.0 <2.1.2"],"fixed":["2.1.2"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.2.0 <2.2.1"],"fixed":["2.2.1"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.3.0 <2.3.1"],"fixed":["2.3.1"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":["<1.15.4"],"fixed":["1.15.4"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.0.0 <2.0.3"],"fixed":["2.0.3"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.1.0 <2.1.2"],"fixed":["2.1.2"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.2.0 <2.2.1"],"fixed":["2.2.1"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.3.0 <2.3.1"],"fixed":["2.3.1"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":["<1.15.4"],"fixed":["1.15.4"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.0.0 <2.0.3"],"fixed":["2.0.3"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.1.0 <2.1.2"],"fixed":["2.1.2"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.2.0 <2.2.1"],"fixed":["2.2.1"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.3.0 <2.3.1"],"fixed":["2.3.1"]}]},{"id":"PYSEC-2020-117","url":"https://osv.dev/vulnerability/PYSEC-2020-117","summary":"","modified":"2023-12-06T01:00:16.273740Z","packages":[{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":["<1.15.4",">=2.0.0 <2.0.3",">=2.1.0 <2.1.2",">=2.2.0 <2.2.1",">=2.3.0 <2.3.1"],"fixed":["1.15.4","2.0.3","2.1.2","2.2.1","2.3.1"]}]},{"id":"PYSEC-2020-274","url":"https://osv.dev/vulnerability/PYSEC-2020-274","summary":"","modified":"2023-12-06T01:00:16.273740Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":["<1.15.4",">=2.0.0 <2.0.3",">=2.1.0 <2.1.2",">=2.2.0 <2.2.1",">=2.3.0 <2.3.1"],"fixed":["1.15.4","2.0.3","2.1.2","2.2.1","2.3.1"]}]},{"id":"PYSEC-2020-309","url":"https://osv.dev/vulnerability/PYSEC-2020-309","summary":"","modified":"2023-12-06T01:00:16.273740Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":["<1.15.4",">=2.0.0 <2.0.3",">=2.1.0 <2.1.2",">=2.2.0 <2.2.1",">=2.3.0 <2.3.1"],"fixed":["1.15.4","2.0.3","2.1.2","2.2.1","2.3.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
