The likely attack vector involves an attacker delivering a specially crafted .keras file to the target system\u2014either through a file upload feature or by instrumenting a training or inference pipeline that consumes user-supplied models. Once executed, the vulnerability permits arbitrary local file reads but requires that the application load the malicious model file; no active network exploitation beyond file delivery is necessary."}}}}, "created": "2026-02-12T10:00:50.946353+00:00", "updated": "2026-04-17T20:15:27.000427+00:00", "vendors": ["google", "google$PRODUCT$keras"]}
