What is CVE-2026-108598?

Floci versions prior to 2.2.0 contain a vulnerability in the VtlTemplateEngine that permits unauthenticated attackers to execute arbitrary commands through uncontrolled Velocity mapping templates. By leveraging this flaw, attackers can manipulate REST API integrations and utilize $util reflection to gain access to Runtime or ProcessBuilder, ultimately executing operating system commands within the Floci Java virtual machine. This poses significant risks to the integrity and security of systems utilizing affected Floci versions.

Affected Version(s)

floci 1.1.0 < 2.2.0
