  "details": "### Summary\n\nThe `PublicKeyBundle.from_dict()` method in `openssl_encrypt/modules/key_bundle.py` at **lines 329-361** creates bundles from untrusted data without verifying the signature. The docstring warns to call `verify_signature()` after creation, but the `to_identity()` method (line 363-391) can convert an unverified bundle directly to an `Identity` object.\n\n### Affected Code\n\n```python\n@classmethod\ndef from_dict(cls, data: Dict) -\u003e \"PublicKeyBundle\":\n    \"\"\"\n    SECURITY: Does NOT verify signature. Call verify_signature() after creation.\n    \"\"\"\n    # Creates bundle without verification\n```\n\n### Impact\n\nIf `from_dict()` followed by `to_identity()` is called without an intervening `verify_signature()` call, encryption could be performed against an attacker\u0027s public key, leaking secrets. While `key_resolver.py` (lines 146-147) does verify before use, the unguarded API path remains directly callable.\n\n### Recommended Fix\n\n- Add a `verified` flag to `PublicKeyBundle` that must be set before `to_identity()` can be called\n- Or have `to_identity()` automatically call `verify_signature()` and raise on failure\n- Or make `from_dict()` require verification as part of construction\n\n### Fix\n\nFixed in commit `f4a1ba6` on branch `releases/1.4.x` \u2014 from_dict() now verifies self_signature by default (verify=True parameter); raises ValueError on verification failure.",
