# Security digest: May 13, 2026

4 critical advisories.

## Take stock

- Go: 2 critical advisories ( github.com/obot-platform/obot , github.com/siyuan-note/siyuan/kernel ). Check with govulncheck ./... .
- npm: 1 critical advisory ( @strapi/content-type-builder , @strapi/plugin-content-type-builder ). Check with npm audit (or: npm ls <package>) .
- Maven: 1 critical advisory ( io.goobi.viewer:viewer-core ). Check with mvn dependency:tree -Dincludes=<groupId>:<artifactId> .
- 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)

None.
