CODESYS Control RTE (SL): Incorrect Resource Transfer Between Spheres

CVE-2025-41660 is a high-severity incorrect resource transfer between spheres vulnerability in CODESYS Control RTE (SL) from Codesys, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user.
