# Security digest: August 2, 2026

1 editorial brief and 1 critical advisory.

## Take stock

- Act now: MLflow CVE-2026-64849: Exploited Unauthenticated SSRF . Teams running MLflow tracking servers 3.3.0 through 3.14.x bound beyond localhost, especially on cloud VMs or Kubernetes nodes with an attached IAM role, service account or managed identity.
- Maven: 1 critical advisory ( org.bouncycastle:bc-fips , org.bouncycastle:bcprov-jdk18on , org.bouncycastle:bcprov-lts8on , org.bouncycastle:bcprov-jdk15to18 ). 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.
