# Security digest: May 3, 2026

1 editorial brief.

## Take stock

- Act now: WSO2 API Manager CVE-2026-5430: Exploited JWT Auth Bypass . Teams running WSO2 API Manager 4.1.0-4.6.0, or API Control Plane, Traffic Manager or Universal Gateway 4.5.0/4.6.0, without the April 2026 update levels or the public fix PRs.
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.
