CVE-2026-24656

What it is

Deserialization of Untrusted Data vulnerability in Apache Karaf Decanter. The Decanter log socket collector exposes the port 4560, without authentication. If the collector exposes allowed classes property, this configuration can be bypassed. It means that the log socket collector is vulnerable to deserialization of untrusted data, eventually causing DoS. NB: Decanter log socket collector is not installed by default. Users who have not installed Decanter log socket are not impacted by this issue. This issue affects Apache Karaf Decanter before 2.12.0. Users are recommended to upgrade to version 2.12.0, which fixes the issue.
