The flaw manifests as a breach of the intended confinement of data within the service, allowing a user with access to the machine to obtain system state, network configuration or other confidential data.

The EPSS score is not available, and it is not listed in the CISA KEV catalog, indicating that no widespread exploitation has been observed yet. The flaw requires authentication to the target machine, so only a local user with sufficient privileges can leverage the issue. Attackers would need to launch code from within the user context that the UPNP service processes, after which they can retrieve the exposed data. Overall, the risk is moderate but mitigable with the vendor\u2019s security patch."}}}}, "created": "2026-04-15T14:41:09.783260+00:00", "updated": "2026-04-15T14:41:09.783272+00:00", "vendors": []}
