Remote Code Execution in Nuance PowerScribe via Deserialization of Untrusted Data
CVE-2026-26142 is a critical remote code execution vulnerability in Nuance PowerScribe, including references to PowerScribe 360 and PowerScribe One. The flaw is caused by deserialization of untrusted data, where the application processes attacker-controlled serialized input in an unsafe manner. According to the provided advisory content, an unauthorized attacker can exploit the issue over the network with low attack complexity, no privileges, and no user interaction. Successful exploitation results in arbitrary code execution in the context of the affected PowerScribe application.
