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 ImpacttotalSuccessful exploitation gives total 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
- 0.51% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Ranks above 41.1% of scored records. A rank, not a probability.
- NVD base score
- 9.9 (CVSS v3.x), scored by the NVD independently of the CNA.
- NVD CVSS vector
- CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
- NVD analysis status
- Analyzed. NVD last modified this record on 2026-07-03.
- 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.

If eXtreme Scale is being used as a Session Cache (Session Grid), this vulnerability is not applicable. In a Session Grid deployment, applications typically use eXtreme Scale only to store and retrieve HTTP session data and do not create or execute Object Query Language (OQL) queries against the session data. As a result, the vulnerable OQL functionality is not exercised.If eXtreme Scale is being used as a Simple Grid and the application executes OQL queries, the risk can be mitigated through application code changes. Recommended mitigation strategies include:1. Never concatenate user-supplied input directly into OQL statements. Use query parameters wherever possible.2. Restrict dynamically specified class names to a predefined allow list of approved classes.3. Do not allow end users to construct or modify OQL query syntax.4. Avoid dynamically loading comparator classes or using reflection-based sorting based on user input.5. Validate and sanitize all user-supplied values before they are used to construct OQL queries.These mitigations help prevent untrusted input from influencing OQL execution and eliminate the attack paths associated with this vulnerability.
