CVSS score 9.8 signals critical severity. EPSS score < 1% suggests a low exploitation probability at present. The vulnerability is not listed in the CISA KEV catalog. Based on the lack of confirmed exploitation, it is inferred that the likelihood of real-world attacks remains uncertain; however, the lack of a publicly disclosed fix or patch status means the residual risk persists.
