SSVC decision
Not assessed by CISA
EPSS probability
0.38% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 32.4% of scored records. A rank, not a probability.
NVD base score
4.7 (CVSS v3.x), scored by the NVD independently of the CNA.
NVD CVSS vector
CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H
NVD analysis status
Modified. NVD last modified this record on 2026-06-17.
Red Hat severity
Low. Red Hat's rating for its own products, not a CVSS rating.

Exploit-prediction scores from FIRST. Independent scoring and analysis status from the NVD. Vendor severity from Red Hat. Exploitation assessment and catalog membership from CISA.
