# Security digest: July 7, 2025

4 known exploited (cisa kev) additions.

## Take stock

- Do you run any of these? Synacor Zimbra Collaboration Suite (ZCS), Rails Ruby on Rails, PHP PHPMailer, Looking Glass Multi-Router Looking Glass (MRLG). They are being exploited in the wild (CISA KEV). Patch or mitigate if you do; CISA’s federal deadline is 2025-07-28.
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.
