# Security digest: July 11, 2023

1 editorial brief.

## Take stock

- Check exposure: ColdFusion CVE-2023-29300/38203: Exploited Pre-Auth RCE . Anyone with a ColdFusion 2018, 2021 or 2023 server, internal or internet-facing, that has not been updated since mid-2023, or a JEE deployment without Adobe's serial filter flag.
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.

## Editorial briefs

## Known exploited (CISA KEV)

None.

## Critical advisories

None.
