The implementation of `ParseAttrValue`(https://github.com/tensorflow/tensorflow/blob/c22d88d6ff33031aa113e48aa3fc9aa74ed79595/tensorflow/core/framework/attr_value_util.cc#L397-L453) can be tricked into stack overflow due to recursion by giving in a specially crafted input. The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-674"],"references":["https://github.com/tensorflow/tensorflow/commit/e07e1c3d26492c06f078c7e5bf2d138043e199c1","https://github.com/tensorflow/tensorflow/security/advisories/GHSA-qw5h-7f53-xrp6","https://github.com/tensorflow/tensorflow/commit/e07e1c3d26492c06f078c7e5bf2d138043e199c1","https://github.com/tensorflow/tensorflow/security/advisories/GHSA-qw5h-7f53-xrp6"],"products":["google:tensorflow"],"source":"nvd","synced_at":"2026-10-19T21:18:09.669877188+00:00"},"epss":{"cve":"CVE-2021-29615","score":0.00204,"percentile":0.10372,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-qw5h-7f53-xrp6","url":"https://osv.dev/vulnerability/GHSA-qw5h-7f53-xrp6","summary":"Stack overflow in `ParseAttrValue` with nested tensors","modified":"2026-09-10T03:49:14.934304123Z","packages":[{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":["<2.1.4"],"fixed":["2.1.4"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.2.0 <2.2.3"],"fixed":["2.2.3"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.3.0 <2.3.3"],"fixed":["2.3.3"]},{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.4.0 <2.4.2"],"fixed":["2.4.2"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":["<2.1.4"],"fixed":["2.1.4"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.2.0 <2.2.3"],"fixed":["2.2.3"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.3.0 <2.3.3"],"fixed":["2.3.3"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.4.0 <2.4.2"],"fixed":["2.4.2"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":["<2.1.4"],"fixed":["2.1.4"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.2.0 <2.2.3"],"fixed":["2.2.3"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.3.0 <2.3.3"],"fixed":["2.3.3"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.4.0 <2.4.2"],"fixed":["2.4.2"]}]},{"id":"PYSEC-2021-252","url":"https://osv.dev/vulnerability/PYSEC-2021-252","summary":"","modified":"2023-12-06T01:01:09.550040Z","packages":[{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":["<2.1.4",">=2.2.0 <2.2.3",">=2.3.0 <2.3.3",">=2.4.0 <2.4.2"],"fixed":["2.1.4","2.2.3","2.3.3","2.4.2"]}]},{"id":"PYSEC-2021-543","url":"https://osv.dev/vulnerability/PYSEC-2021-543","summary":"","modified":"2023-12-06T01:01:09.550040Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":["<2.1.4",">=2.2.0 <2.2.3",">=2.3.0 <2.3.3",">=2.4.0 <2.4.2"],"fixed":["2.1.4","2.2.3","2.3.3","2.4.2"]}]},{"id":"PYSEC-2021-741","url":"https://osv.dev/vulnerability/PYSEC-2021-741","summary":"","modified":"2023-12-06T01:01:09.550040Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":["<2.1.4",">=2.2.0 <2.2.3",">=2.3.0 <2.3.3",">=2.4.0 <2.4.2"],"fixed":["2.1.4","2.2.3","2.3.3","2.4.2"]}]}],"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).
