- Not assessed by CISA
- EPSS probability
- 1.79% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 78.0% of scored records. A rank, not a probability.
- NVD base score
- 4.6 (CVSS v3.x), scored by the NVD independently of the CNA.
- NVD CVSS vector
- CVSS:3.0/AV:P/AC:L/PR:N/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.
