{"id":"PYSEC-2026-2547","summary":"Keras has an untrusted deserialization vulnerability","details":"A vulnerability in the `TFSMLayer` class of the `keras` package, version 3.13.0, allows attacker-controlled TensorFlow SavedModels to be loaded during deserialization of `.keras` models, even when `safe_mode=True`. This bypasses the security guarantees of `safe_mode` and enables arbitrary attacker-controlled code execution during model inference under the victim's privileges. The issue arises due to the unconditional loading of external SavedModels, serialization of attacker-controlled file paths, and the lack of validation in the `from_config()` method.","aliases":["CVE-2026-1462","GHSA-4f3f-g24h-fr8m"],"modified":"2026-07-13T16:32:00.924214170Z","published":"2026-07-13T15:02:47.434341Z","references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-1462"},{"type":"WEB","url":"https://github.com/keras-team/keras/pull/22035"},{"type":"WEB","url":"https://github.com/keras-team/keras/commit/b6773d3decaef1b05d8e794458e148cb362f163f"},{"type":"PACKAGE","url":"https://github.com/keras-team/keras"},{"type":"WEB","url":"https://huntr.com/bounties/7e78d6f1-6977-4300-b595-e81bdbda331c"},{"type":"PACKAGE","url":"https://pypi.org/project/keras"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-4f3f-g24h-fr8m"}],"affected":[{"package":{"name":"keras","ecosystem":"PyPI","purl":"pkg:pypi/keras"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.13.2"}]}],"versions":["0.2.0","0.3.0","0.3.1","0.3.2","0.3.3","1.0.0","1.0.1","1.0.2","1.0.3","1.0.4","1.0.5","1.0.6","1.0.7","1.0.8","1.1.0","1.1.1","1.1.2","1.2.0","1.2.1","1.2.2","2.0.0","2.0.1","2.0.2","2.0.3","2.0.4","2.0.5","2.0.6","2.0.7","2.0.8","2.0.9","2.1.0","2.1.1","2.1.2","2.1.3","2.1.4","2.1.5","2.1.6","2.10.0","2.10.0rc0","2.10.0rc1","2.11.0","2.11.0rc0","2.11.0rc1","2.11.0rc2","2.11.0rc3","2.12.0","2.12.0rc0","2.12.0rc1","2.13.1","2.13.1rc0","2.13.1rc1","2.14.0","2.14.0rc0","2.15.0","2.15.0rc0","2.15.0rc1","2.2.0","2.2.1","2.2.2","2.2.3","2.2.4","2.2.5","2.3.0","2.3.1","2.4.0","2.4.1","2.4.2","2.4.3","2.5.0rc0","2.6.0","2.6.0rc0","2.6.0rc1","2.6.0rc2","2.6.0rc3","2.7.0","2.7.0rc0","2.7.0rc2","2.8.0","2.8.0rc0","2.8.0rc1","2.9.0","2.9.0rc0","2.9.0rc1","2.9.0rc2","3.0.0","3.0.1","3.0.2","3.0.3","3.0.4","3.0.5","3.1.0","3.1.1","3.10.0","3.11.0","3.11.1","3.11.2","3.11.3","3.12.0","3.12.1","3.12.2","3.12.3","3.13.0","3.13.1","3.2.0","3.2.1","3.3.0","3.3.1","3.3.2","3.3.3","3.4.0","3.4.1","3.5.0","3.6.0","3.7.0","3.8.0","3.9.0","3.9.1","3.9.2"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/keras/PYSEC-2026-2547.yaml"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
