Recent
- 7.5HighSep 30, 2026CODESYS Development System 3 Denial of serviceCVE-2026-76992The CODESYS Gateway Client allocates memory based on a size field in a gateway response without enforcing an appropriate upper limit. An unauthenticated remote attacker controlling a malicious gateway can exploit this behavior to trigger excessive memory consumption, resulting in a denial-of-service condition thus leading to a total loss of availablity.
- 8.1HighSep 30, 2026CODESYS Control RTE (SL)CVE-2026-79625Affected products do not properly synchronize access to their monitoring functionality. When multiple clients send concurrent requests, this may lead to incorrect reads or writes, or to corruption of internal memory structures. An authenticated remote attacker with monitoring access can exploit this issue to cause incorrect data processing or a denial-of-service condition.
- 7.8HighMay 26, 2026Codesys development system Privilege escalationCVE-2026-44469The affected product extracts installation files to a temporary directory with incorrect default permissions during administrative installation. A low-privileged local attacker can exploit a TOCTOU race condition with a practical time window to replace verified files with malicious ones before installation, resulting in local privilege escalation.
- 7.8HighMay 26, 2026Codesys development system Privilege escalationCVE-2026-44468The affected product creates a directory with insecure default permissions during administrative installation. This allows a low-privileged local attacker to modify a temporary file defining the components to be installed, enabling local privilege escalation by forcing the deployment of arbitrary components.
- 6.5MediumMay 21, 2026Codesys visualizationCVE-2026-0393The affected product may expose credentials remotely between low privileged visualization users during concurrent login operations due to insufficient isolation of authentication data. The vulnerability affects only login operations within an active visualization session.
- 7.5HighDec 1, 2025Codesys control for beaglebone sl Memory corruptionCVE-2025-41738An unauthenticated remote attacker may cause the visualisation server of the CODESYS Control runtime system to access a resource with a pointer of wrong type, potentially leading to a denial-of-service (DoS) condition.
- 7.8HighDec 1, 2025codesys DeserializationCVE-2025-41700An unauthenticated attacker can trick a local user into executing arbitrary code by opening a deliberately manipulated CODESYS project file with a CODESYS development system. This arbitrary code is executed in the user context.
