# Security digest: December 29, 2025

1 known exploited (cisa kev) addition.

## Take stock

- Do you run any of these? MongoDB MongoDB and MongoDB Server. They are being exploited in the wild (CISA KEV). Patch or mitigate if you do; CISA’s federal deadline is 2026-01-19.
- 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-2025-14847](https://erroneo.us/security/cve/CVE-2025-14847/index.md) MongoDB MongoDB and MongoDB Server: MongoDB and MongoDB Server Improper Handling of Length Parameter Inconsistency Vulnerability (CISA due 2026-01-19)

## Critical advisories

None.
