CVE-2026-108598
Floci 1.1.0 before 2.2.0 contains a code injection vulnerability in VtlTemplateEngine that allows unauthenticated attackers to execute commands via unrestricted Velocity mapping templates.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.93%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Floci 1.1.0 before 2.2.0 contains a code injection vulnerability in VtlTemplateEngine that allows unauthenticated attackers to execute commands via unrestricted Velocity mapping templates. Attackers can create a REST API with a MOCK integration whose template uses $util reflection to reach Runtime or ProcessBuilder, executing OS commands in the Floci JVM.
