How to Fix CVE-2022-36447

To remediate this vulnerability, upgrade all affected Chia blockchain dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

chia-blockchain fixed: Latest secure release 
pip install chia-blockchain>=Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show chia-blockchain

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2022-36447, inspect your installed packages using pip:

pip show chia-blockchain

Analyze the terminal output to locate any version of Chia blockchain in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The pip show chia-blockchain command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Chia blockchain, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

An inflation issue was discovered in Chia Network CAT1 Standard 1.0.0. Previously minted tokens minted on the Chia blockchain using the CAT1 standard can be inflated to an arbitrary extent by any holder of any amount of the token. The total amount of the token can be increased as high as the malicious actor pleases. This is true for every CAT1 on the Chia blockchain regardless of issuance rules. This attack is auditable on chain, so maliciously altered coins can potentially be marked by off-chain observers as malicious.
