CVE-2026-26142 is a critical remote code execution vulnerability in Nuance PowerScribe, including references indicating impact to PowerScribe 360 and PowerScribe One. The flaw is caused by deserialization of untrusted data (CWE-502), 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. Microsoft assigned CVSS 3.1 vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H and a base score of 9.8. Successful exploitation allows arbitrary code execution in the context of the affected PowerScribe application.
