{"id":"CVE-2026-12482","aliases":["GHSA-58hv-7753-xmfq","PYSEC-2026-3630"],"url":"https://o3.security/vulnerability/CVE-2026-12482","summary":"Path Traversal via Symlink Name Validation Bypass in keras-team/keras","details":"A vulnerability in keras-team/keras version 3.12.0 allows an attacker to craft a malicious tar archive that bypasses the `filter_safe_tarinfos` validation in `keras/src/utils/file_utils.py`. Specifically, symlink entries are not subjected to the same `is_path_in_dir` validation as regular file entries, allowing symlinks to be created outside the intended extraction directory. This can lead to symlink-based file read, file overwrite, or directory escape attacks. The issue is particularly impactful on Python 3.10 and 3.11, where `filter_safe_tarinfos` is the sole defense against tar path traversal. This vulnerability is distinct from CVE-2025-12060 and other previously reported issues.","published":"2026-07-14T05:13:07.252Z","modified":"2026-08-12T03:51:39.201171496Z","cvss":{"score":3.1,"severity":"LOW","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N"},"epss":{"score":0.00238,"percentile":0.1504,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"keras","fixedVersion":"3.12.3"},{"ecosystem":"PyPI","name":"keras","fixedVersion":"3.15.0"}],"fix":{"url":"https://github.com/keras-team/keras/pull/23015","label":"keras-team/keras#23015"},"references":[{"type":"WEB","url":"https://huntr.com/bounties/5d3638e8-a9f6-4964-a865-ddb9fe4d4b6e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/12xxx/CVE-2026-12482.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-12482"},{"type":"WEB","url":"https://github.com/keras-team/keras/pull/23015"},{"type":"WEB","url":"https://github.com/keras-team/keras/pull/23165"},{"type":"WEB","url":"https://github.com/keras-team/keras/commit/9867df45c456dd1077a6243bb56219f66e288150"},{"type":"WEB","url":"https://github.com/keras-team/keras/commit/d338a45204bdc787c8b3c4a9b82c1911cd52dedf"},{"type":"PACKAGE","url":"https://github.com/keras-team/keras"},{"type":"WEB","url":"https://github.com/keras-team/keras/releases/tag/v3.12.3"},{"type":"WEB","url":"https://github.com/keras-team/keras/releases/tag/v3.15.0"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:39.201171496Z"}}
