Specifically, the `_raise_for_lambda_deserialization()` function fails to enforce the safe-mode guard when `safe_mode` is set to `None`, which is the default value when `from_config()` is called outside of a `SafeModeScope` context. This logic error conflates `None` (unset/default-deny) with `False` (explicitly disabled), bypassing the guard and allowing attacker-controlled `marshal` bytecode to be deserialized. Affected call sites include `keras.layers.deserialize(config)`, `keras.models.clone_model(model)`, and any direct invocation of `Lambda.from_config(config)` without an enclosing `SafeModeScope(True)`. This vulnerability can be exploited to achieve arbitrary OS-level code execution in the context of the server or user process."}],"affected":[{"vendor":"keras-team","product":"keras-team/keras","versions":[{"version":"unspecified","status":"affected","versionType":"custom","lessThanOrEqual":"latest"}]}],"references":[{"url":"https://huntr.com/bounties/59ceaed1-c8a3-4135-8f94-169ade02823d"}],"metrics":[{"cvssV3_0":{"version":"3.0","attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"HIGH","confidentialityImpact":"HIGH","integrityImpact":"HIGH","privilegesRequired":"NONE","scope":"UNCHANGED","userInteraction":"REQUIRED","vectorString":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH"}}],"problemTypes":[{"descriptions":[{"type":"CWE","lang":"en","description":"CWE-502 Deserialization of Untrusted Data","cweId":"CWE-502"}]}],"source":{"advisory":"59ceaed1-c8a3-4135-8f94-169ade02823d","discovery":"EXTERNAL"}},"adp":[{"references":[{"url":"https://huntr.com/bounties/59ceaed1-c8a3-4135-8f94-169ade02823d","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-06T15:15:34.297007Z","id":"CVE-2026-12481","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-07-06T15:15:46.244Z"}}]}}
