# Security digest: September 23, 2025

1 known exploited (cisa kev) addition and 1 critical advisory.

## Take stock

- Do you run any of these? Google Chromium V8. They are being exploited in the wild (CISA KEV). Patch or mitigate if you do; CISA’s federal deadline is 2025-10-14.
- NuGet: 1 critical advisory ( DotNetNuke.Core ). Check with dotnet list package --vulnerable --include-transitive .
- 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)

- [CVE-2025-10585](https://erroneo.us/security/cve/CVE-2025-10585/index.md) Google Chromium V8: Google Chromium V8 Type Confusion Vulnerability (CISA due 2025-10-14)

## Critical advisories
