This scores high on paper (CVSS 8) but the real-world signal is low. It is not in CISA KEV and no public exploit was found, and near-term exploitation looks unlikely (EPSS about 0%). Verify your own exposure before treating it as urgent. Not an emergency for most teams, but patch it in your normal cycle and check whether the affected component is actually exposed in your setup.
