CVE-2026-12569 is a critical remote code execution vulnerability affecting PTC Windchill PDMLink and PTC FlexPLM. The flaw is described as deserialization of untrusted data, with some advisories also characterizing it as improper input validation. A remote attacker can send a crafted network request that causes unsafe processing of attacker-controlled serialized data, resulting in arbitrary code execution on the target application server. Reporting indicates the issue affects all CPS versions and Windchill and FlexPLM releases prior to 11.0 M030, with additional affected release lines referenced in vendor and third-party reporting. The vulnerability has been observed in active exploitation and has been associated with deployment of JSP web shells and follow-on data theft activity.
