CVE-2024-0960
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability was found in flink-extended ai-flow 0.3.1. It has been declared as critical. Affected by this vulnerability is the function cloudpickle.loads of the file \ai_flow\cli\commands\workflow_command.py. The manipulation leads to deserialization. The attack can be launched remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used. The identifier VDB-252205 was assigned to this vulnerability.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceDeserialization vulnerability in flink-extended ai-flow 0.3.1 where the cloudpickle.loads() function in the CLI workflow command handler deserializes untrusted data, potentially allowing remote code execution. The vulnerability is remotely exploitable but requires high complexity.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed Aiflow versionRun 'pip show ai-flow' or check the package version in your Python environment to confirm the exact version installedAffected if The version is exactly 0.3.1
-
Locate cloudpickle usage in CLI handlerSearch the codebase for files containing 'cloudpickle.loads' in the CLI workflow command handling codeAffected if The cloudpickle.loads() function is present in the CLI workflow command handler module
-
Verify the vulnerable code path is reachableCheck if the CLI workflow command handler is enabled or used in your deployment configurationAffected if The CLI workflow command handler is actively processing incoming requests or commands containing serialized data
-
Confirm cloudpickle deserializes external inputReview the code flow from the command handler to cloudpickle.loads() to verify it processes untrusted serialized dataAffected if The application accepts serialized data from network sources and passes it directly to cloudpickle.loads() without validation
You are affected if you are running Flink Extended Aiflow version 0.3.1 and your deployment enables the CLI workflow command handler that uses cloudpickle.loads() to deserialize untrusted data.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataReplace cloudpickle.loads() with safe deserialization methods or implement cryptographic validation of serialized data before deserialization. Audit all serialization/deserialization paths in the codebase.
