# Security digest: July 20, 2025

1 known exploited (cisa kev) addition.

## Take stock

- Do you run any of these? Microsoft SharePoint. They are being exploited in the wild (CISA KEV). Patch or mitigate if you do; CISA’s federal deadline is 2025-07-21.
- 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-2025-53770](https://erroneo.us/security/cve/CVE-2025-53770/index.md) Microsoft SharePoint: Microsoft SharePoint Deserialization of Untrusted Data Vulnerability (CISA due 2025-07-21)

## Critical advisories

None.
