CVE-2025-46548: Akka Management

Medium severity, CVSS 6.5. EPSS: 0.7% chance of exploitation in the next 30 days.

If you enable Basic Authentication in Pekko Management using the Java DSL, the authenticator may not be properly applied. Users that rely on authentication instead of making sure the Management API ports are only available to trusted users are recommended to upgrade to version 1.1.1, which fixes this issue. Akka was affected by the same issue and has released the fix in version 1.6.1.

Affected products

• Akka Akka Management: before 1.6.1 (fixed in 1.6.1)
• Apache Pekko Management: from 1.0.0, up to and including 1.1.1
