Authenticated code execution via unsigned boot application
Published Mar 24, 2026 · Updated Mar 24, 2026
Code execution in affected CODESYS Control V3 runtimes allows remote authenticated users to run arbitrary code on the PLC. The CmpApp component lets Service-group users replace the boot application without cryptographic validation when application signing is not enforced. Exploitation requires Service-level file permissions and permits attacker-supplied code to execute when the controller loads the replacement application.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0.0.0 <4.21.0.0
