Critical Vulnerability in NestJS Devtools: Localhost RCE via Sandbox Escape
A flawed sandbox in @nestjs/devtools-integration lets attackers run code on your machine via CSRF, leading to full Remote Code Execution (RCE).
Polygon ETL lets you convert blockchain data into convenient formats like CSVs and relational databases.
Full documentation available here.
Install Polygon ETL CLI:
pip3 install polygon-etl
Export blocks, actions and logs (Schema, Reference):
> polygonetl export_blocks_and_transactions --start-block 0 --end-block 500000 \
--provider-uri grpcs://api.mainnet.polygon.one:443 \
--blocks-output blocks.csv --transactions-output transactions.csv
Stream blocks, actions and logs to console (Reference):
> pip3 install polygon-etl[streaming]
> polygonetl stream --start-block 500000 -e block,action,log --log-file log.txt \
--provider-uri grpcs://api.mainnet.polygon.one:443

For the latest version, check out the repo and call
> pip3 install -e .
> python3 polygonetl.py
> pip3 install -r ../requirements_test.txt -e .[streaming]
> export POLYGONETL_RUN_SLOW_TESTS=true
> export POLYGONETL_PROVIDER_URI=grpcs://api.mainnet.polygon.one:443
> pytest -vv
> pip3 install -r ../requirements_test.txt
> export POLYGONETL_RUN_SLOW_TESTS=true

Install Docker https://docs.docker.com/install/
Build a docker image
> docker build -t polygon-etl:latest .
> docker image ls
Run a container out of the image
> docker run -v $HOME/output:/polygon-etl/output polygon-etl:latest export_blocks -s 1 -e 5499999 -b 1000 -o out
Run streaming to console or Pub/Sub
> docker build -t polygon-etl:latest -f Dockerfile .
> echo "Stream to console"
> docker run polygon-etl:latest stream --start-block 500000 --log-file log.txt
> echo "Stream to Pub/Sub"
> docker run -v /path_to_credentials_file/:/polygon-etl/ --env GOOGLE_APPLICATION_CREDENTIALS=/polygon-etl/credentials_file.json polygon-etl:latest stream --start-block 500000 --output projects/<your-project>/topics/mainnet
