{"id":"PYSEC-2026-3804","summary":"Accelerate path traversal and denial of service via sharded checkpoint weight_map entries","details":"Hugging Face Accelerate through 1.14.0 contains a path traversal vulnerability in load_checkpoint_in_model and load_checkpoint_and_dispatch functions that fail to sanitize weight_map entries from sharded checkpoint indexes. Attackers can supply relative paths with ../ sequences or absolute paths to read arbitrary files, or point shard entries at named pipes to cause indefinite blocking and denial of service.","aliases":["CVE-2026-69112","GHSA-4j2p-28q2-5m79"],"modified":"2026-09-10T12:15:02.997766943Z","published":"2026-09-10T09:44:51.517506Z","references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-69112"},{"type":"WEB","url":"https://github.com/huggingface/accelerate/issues/4067"},{"type":"WEB","url":"https://github.com/huggingface/accelerate/pull/4070"},{"type":"WEB","url":"https://github.com/huggingface/accelerate/pull/4138"},{"type":"PACKAGE","url":"https://github.com/huggingface/accelerate"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/hugging-face-accelerate-path-traversal-and-dos-via-weight-map"},{"type":"PACKAGE","url":"https://pypi.org/project/accelerate"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-4j2p-28q2-5m79"}],"affected":[{"package":{"name":"accelerate","ecosystem":"PyPI","purl":"pkg:pypi/accelerate"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"1.14.0"}]}],"versions":["0.0.1","0.1.0","0.10.0","0.11.0","0.12.0","0.13.0","0.13.1","0.13.2","0.14.0","0.15.0","0.16.0","0.17.0","0.17.1","0.18.0","0.19.0","0.2.0","0.2.1","0.20.0","0.20.1","0.20.2","0.20.3","0.21.0","0.22.0","0.23.0","0.24.0","0.24.1","0.25.0","0.26.0","0.26.1","0.27.0","0.27.1","0.27.2","0.28.0","0.29.0","0.29.1","0.29.2","0.29.3","0.3.0","0.30.0","0.30.0rc0","0.30.1","0.31.0","0.32.0","0.32.1","0.33.0","0.34.0","0.34.1","0.34.2","0.4.0","0.5.0","0.5.1","0.6.0","0.6.1","0.6.2","0.7.0","0.7.1","0.8.0","0.9.0","1.0.0","1.0.0rc0","1.0.0rc1","1.0.1","1.1.0","1.1.1","1.10.0","1.10.1","1.11.0","1.12.0","1.13.0","1.14.0","1.2.0","1.2.1","1.3.0","1.4.0","1.5.0","1.5.1","1.5.2","1.6.0","1.7.0","1.8.0","1.8.1","1.9.0"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/accelerate/PYSEC-2026-3804.yaml"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
