{"id":"CVE-2026-12570","state":"PUBLISHED","title":"Denial of Service via HDF5 Shape Bomb in keras.models.load_model() in keras-team/keras","description":"A vulnerability in keras-team/keras versions <= 3.15.0 allows for a denial of service (DoS) attack when loading malicious .keras model files via the keras.models.load_model() function. The H5IOStore.__getitem__ method in keras/src/saving/saving_lib.py does not validate the shape or size of datasets, leading to unbounded memory allocation. A specially crafted .keras file can exploit this flaw to trigger an out-of-memory (OOM) condition, causing the process to be terminated (exit code 137). This issue bypasses the fix for CVE-2026-0897, which only addressed a similar vulnerability in KerasFileEditor. The attack vector includes poisoned models from public repositories or malicious model registries, posing a risk to machine learning pipelines that process untrusted models.","publishedAt":"2026-08-10T06:29:56.111Z","updatedAt":"2026-08-10T17:37:39.037Z","severity":{"score":5.5,"label":"Medium","version":"3.0","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","source":"@huntr_ai"},"assigner":"@huntr_ai","products":["keras-team keras-team/keras"],"affected":[{"vendor":"keras-team","product":"keras-team/keras","versions":[{"version":"unspecified","status":"affected","lessThan":"3.12.3, 3.15.0","versionType":"custom"}]}],"references":["https://huntr.com/bounties/a064f475-780a-409a-82f7-678512f27ad8","https://github.com/keras-team/keras/commit/4933ea4a5b3fcc24ceacdc276f5bb5dfbd06756c"],"weaknesses":["CWE-770"],"ingestedAt":"2026-10-29T20:10:52.580Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/12xxx/CVE-2026-12570.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-12570","state":"PUBLISHED","datePublished":"2026-08-10T06:29:56.111Z","dateUpdated":"2026-08-10T17:37:39.037Z","assignerShortName":"@huntr_ai","assignerOrgId":"c09c270a-b464-47c1-9133-acb35b22c19a","dateReserved":"2026-06-18T01:55:25.311Z"},"containers":{"cna":{"title":"Denial of Service via HDF5 Shape Bomb in keras.models.load_model() in keras-team/keras","descriptions":[{"lang":"en","value":"A vulnerability in keras-team/keras versions <= 3.15.0 allows for a denial of service (DoS) attack when loading malicious .keras model files via the keras.models.load_model() function.
