# Security digest: August 1, 2024

2 critical advisories.

## Take stock

- Go: 2 critical advisories ( github.com/mattermost/mattermost/server/v8 ). Check with govulncheck ./... .
- 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.
