# Security digest: June 8, 2023

1 editorial brief.

## Take stock

- Check exposure: PaperCut NG/MF CVE-2023-2533: 2023 CSRF Added to KEV in 2025 . Anyone running a PaperCut NG or MF Application Server older than 22.1.1 (other than 21.2.12 or 20.1.8), and anyone on version 23 or earlier, which gets no fix for the 2026 PaperCut bugs.
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.

## Editorial briefs

- **Check exposure** [PaperCut NG/MF CVE-2023-2533: 2023 CSRF Added to KEV in 2025](https://erroneo.us/security/briefs/papercut-ng-mf-cve-2023-2533-csrf-kev/index.md): This 2023 CSRF needs a logged-in admin to be lured to a page, but any PaperCut server old enough to have it is also open to later, mass-exploited PaperCut bugs; find such servers and move them to a current release.

## Known exploited (CISA KEV)

None.

## Critical advisories

None.
