{"cve":"CVE-2020-26269","nvd":{"published":"2020-12-10T23:15:12.910","modified":"2026-06-17T03:07:57.907","status":"Modified","description":"In TensorFlow release candidate versions 2.4.0rc*, the general implementation for matching filesystem paths to globbing pattern is vulnerable to an access out of bounds of the array holding the directories. There are multiple invariants and preconditions that are assumed by the parallel implementation of GetMatchingPaths but are not verified by the PRs introducing it (#40861 and #44310). Thus, we are completely rewriting the implementation to fully specify and validate these. This is patched in version 2.4.0. This issue only impacts master branch and the release candidates for TF version 2.4. The final release of the 2.4 release will be patched.","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:H","score":7.5},"cwes":["CWE-125"],"references":["https://github.com/tensorflow/tensorflow/commit/8b5b9dc96666a3a5d27fad7179ff215e3b74b67c","https://github.com/tensorflow/tensorflow/security/advisories/GHSA-9jjw-hf72-3mxw","https://github.com/tensorflow/tensorflow/commit/8b5b9dc96666a3a5d27fad7179ff215e3b74b67c","https://github.com/tensorflow/tensorflow/security/advisories/GHSA-9jjw-hf72-3mxw"],"products":["google:tensorflow"],"source":"nvd","synced_at":"2026-10-19T21:12:09.559580076+00:00"},"epss":{"cve":"CVE-2020-26269","score":0.00697,"percentile":0.53074,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-9jjw-hf72-3mxw","url":"https://osv.dev/vulnerability/GHSA-9jjw-hf72-3mxw","summary":"TensorFlow vulnerable to heap out of bounds read in filesystem glob matching","modified":"2026-09-10T03:49:46.420066944Z","packages":[{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.4.0rc0 <2.4.0"],"fixed":["2.4.0"]},{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.4.0rc0 <2.4.0"],"fixed":["2.4.0"]},{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.4.0rc0 <2.4.0"],"fixed":["2.4.0"]}]},{"id":"PYSEC-2020-141","url":"https://osv.dev/vulnerability/PYSEC-2020-141","summary":"","modified":"2023-12-06T01:00:27.809388Z","packages":[{"ecosystem":"PyPI","name":"tensorflow","purl":"pkg:pypi/tensorflow","ranges":[">=2.4.0rc0 <2.4.0"],"fixed":["2.4.0"]}]},{"id":"PYSEC-2020-300","url":"https://osv.dev/vulnerability/PYSEC-2020-300","summary":"","modified":"2023-12-06T01:00:27.809388Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-cpu","purl":"pkg:pypi/tensorflow-cpu","ranges":[">=2.4.0rc0 <2.4.0"],"fixed":["2.4.0"]}]},{"id":"PYSEC-2020-335","url":"https://osv.dev/vulnerability/PYSEC-2020-335","summary":"","modified":"2023-12-06T01:00:27.809388Z","packages":[{"ecosystem":"PyPI","name":"tensorflow-gpu","purl":"pkg:pypi/tensorflow-gpu","ranges":[">=2.4.0rc0 <2.4.0"],"fixed":["2.4.0"]}]}],"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).
