Security readout for executives and security teams
A malicious OpenDocument file can crash and potentially take over Hyland Perceptive Document Filters 11.4.0.2647. Business risk is highest where the product processes externally supplied documents for preview, indexing, conversion, or upload workflows. Exposure is likely limited to organizations running Hyland Perceptive Document Filters 11.4.0.2647 on Windows or Linux, especially in document ingestion, rendering, indexing, or conversion pipelines that accept OpenDocument files. Treat this as a high-priority remediation item if the affected product processes external documents. It is not listed as actively exploited in the provided sources, but successful exploitation could allow code execution in a business document pipeline. Mitigation focus: Check Hyland and Talos guidance for fixed versions or vendor-recommended remediation.; Prioritize upgrade or replacement of Perceptive Document Filters 11.4.0.2647 where present.; Restrict processing of untrusted OpenDocument files until remediation is confirmed..
