Unknown · Cron-Utils · CVE-2021-41269
**Name of the Vulnerable Software and Affected Versions**
cron-utils versions up to 9.1.2
**Description**
A template injection issue was identified in cron-utils, enabling attackers to inject arbitrary Java EL expressions, leading to unauthenticated Remote Code Execution (RCE). This issue affects projects using the `@Cron` annotation to validate untrusted Cron expressions.
**Recommendations**
For versions up to 9.1.2, please upgrade to version 9.1.6 to resolve the issue. As a temporary workaround, consider avoiding the use of the `@Cron` annotation to validate untrusted Cron expressions until the patch is applied. There are no known workarounds other than upgrading to the patched version.
