SSVC decision
Not assessed by CISA
EPSS probability
1.20% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 67.7% of scored records. A rank, not a probability.
NVD base score
5.3 (CVSS v3.x), scored by the NVD independently of the CNA.
NVD CVSS vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
NVD analysis status
Modified. NVD last modified this record on 2026-06-17.
