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.
- AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
- 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
- 0.15% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Ranks above 4.8% of scored records. A rank, not a probability.
- NVD base score
- 2.3 (CVSS v4.0), scored by the NVD independently of the CNA.

- NVD analysis status
- Awaiting Analysis. NVD last modified this record on 2026-08-31.
- Red Hat severity
- No Red Hat rating. Red Hat rates the CVEs that affect its products.
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.

SRC: CNA
Upgrade Kong Event Gateway to version 1.1.2 (for the 1.1.x branch or 1.0.x which is no longer supported) or 1.2.1 (for the 1.2.x branch). These versions enforce automatic key rotation before the NIST-recommended usage limit is reached.
