# Security digest: October 1, 2025

2 critical advisories.

## Take stock

- crates.io (Rust): 1 critical advisory ( risc0-zkvm-platform , risc0-zkos-v1compat , risc0-aggregation , risc0-zkvm ). Check with cargo audit .
- PyPI: 1 critical advisory ( pyfory , pyfury ). Check with pip-audit (or: pip show <package>) .
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.

## Known exploited (CISA KEV)

None.
