Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.pekko:pekko-management_2.12, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2025-46548 if there is no patch (or I can't update yet)?

Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.

Is CVE-2025-46548 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-46548 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Description

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.
