03 Exploitation and scoring
- 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.
- EPSS probability
- 6.09% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 93.3% of scored records. A rank, not a probability.
- NVD base score
- 10.0 (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:H/I:H/A:H
- NVD analysis status
- Analyzed. NVD last modified this record on 2026-10-25.

Vulnerability is not applicable if Transport protocol is not Object Request Broker (ORB) rather IBM eXtremeIO (XIO) .Please do not use ORB as transport protocol and use XIO as transport protocol. Please follow the below document for setting XIO as transport protocol https://www.ibm.com/docs/en/SSTVLU_8.6.1/com.ibm.websphere.extremescale.doc/txsconfigxstransport.html ORB is deprecated and we have removed ORB support from 8.6.2.* version . We recommend customers to migrate to 8.6.2.*.
