Horovod versions up to and including v0.28.1 are vulnerable to unauthenticated remote code execution. The vulnerability is due to improper handling of base64-encoded data in the ElasticRendezvousHandler, a subclass of KVStoreHandler. Specifically, the putvalue method in ElasticRendezvousHandler calls codec.loadsbase64(value), which eventually invokes cloudpickle.loads(decoded). This allows an attacker to send a malicious pickle object via a PUT request, leading to arbitrary code execution on the server.

Uber Kraken through 0.1.29 fails to validate the tag parameter in the /tags/{tag} endpoint, allowing unauthenticated attackers to traverse outside the configured storage root. Attackers can use percent-encoded parent-directory segments in the tag parameter to read arbitrary files accessible to the testfs backend process.

greykite v1.0.0 was discovered to contain an arbitrary file upload vulnerability in the loadobj function at /templates/pickleutils.py. This vulnerability allows attackers to execute arbitrary code via uploading a crafted file.

Uber Technologies, Inc. UberEATS: Uber for Food Delivery, 1.108.10001, 2017-11-02, iOS application uses a hard-coded key for encryption. Data stored using this key can be decrypted by anyone able to access this key.

kraken <= 0.1.4 has an arbitrary file read vulnerability via the component testfs.
