03 Exploitation and scoring
SRC: CISA, FIRST, NVD, RED HAT- Exploitation
- Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
- SSVC decision
- ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
- AutomatableyesAn attacker can reliably automate reconnaissance through exploitation, so this scales.
- Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.- EPSS probability
- 0.22% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Ranks above 13.2% of scored records. A rank, not a probability.
- NVD base score
- 5.8 (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:C/C:L/I:N/A:N
- NVD analysis status
- Analyzed. NVD last modified this record on 2026-06-17.
- Red Hat severity

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.

Upgrade to versions 18.9.7, 18.10.6, 18.11.3 or above. Additionally, review the Jira API token used in your integration and ensure it is scoped to only the Jira projects you intend to expose. The project keys field in the integration configuration filters the displayed issues but does not restrict the token's access. To limit which issues can be read through the integration, generate the API token from a Jira account with access only to the desired projects.
