Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache Karaf Decanter's Log Socket Collector (org.apache.karaf.decanter.collector.log.socket) before 2.12.0 is vulnerable to deserialization of untrusted data. The collector listens on port 4560 without authentication, and an attacker with network access to that port can bypass the allowed classes setting, which can cause a denial of service. Upgrade to version 2.12.0, which fixes the issue. Only installations that have the Log Socket Collector installed are affected.
