Real, but low real-world risk

A genuine vulnerability on paper, but EPSS shows little real-world exploitation — the base score may overstate urgency. This is not the same as a false positive.

    This scores high on paper (CVSS 7.8) 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 1%). Verify your own exposure before treating it as urgent. It needs local access, so it reads more as a privilege-escalation or post-access risk than a remote one. 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.
