Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (4.20%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Cron-utils is a Java library to parse, validate, migrate crons as well as get human readable descriptions for them. In cron-utils before version 9.1.3, a template Injection vulnerability is present. This enables attackers to inject arbitrary Java EL expressions, leading to unauthenticated Remote Code Execution (RCE) vulnerability. Only projects using the @Cron annotation to validate untrusted Cron expressions are affected. This issue was patched in version 9.1.3.
