# Security digest: January 2, 2024

2 known exploited (cisa kev) additions and 1 critical advisory.

## Take stock

- Do you run any of these? Spreadsheet::ParseExcel Spreadsheet::ParseExcel, Google Chromium WebRTC. They are being exploited in the wild (CISA KEV). Patch or mitigate if you do; CISA’s federal deadline is 2024-01-23.
- Composer (PHP): 1 critical advisory ( plotly/plotly.js ). Check with composer audit .
- npm: 1 critical advisory ( plotly.js ). Check with npm audit (or: npm ls <package>) .
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.
