CVE-2026-123374
critical
Description
Deserialization of Untrusted Data vulnerability in Apache Roller. When Roller sends a weblog update ping, its XML-RPC client deserializes Java object data contained in the ping target's response, so a party that controls that response can run code in the Roller server process. This issue affects Apache Roller from 4.0 through 6.1.6. Users are recommended to upgrade to version 6.1.7, which removes the unsafe deserialization.
