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
- 0.45% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Ranks above 37.4% of scored records. A rank, not a probability.
- NVD base score
- 7.5 (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:U/C:N/I:N/A:H
- NVD analysis status
- Modified. NVD last modified this record on 2026-06-17.
- 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.

IBM strongly recommends addressing the vulnerability now by applying a currently available interim fix or fix pack that contains the fix for APAR PH66953. To determine if a feature is enabled for IBM WebSphere Application Server Liberty, refer to How to determine if Liberty is using a specific feature. To determine if the HTTP/2 protocol is enabled with Liberty Servlet features see HTTP/2 Support for Liberty.
For IBM WebSphere Application Server Liberty 18.0.0.2 - 25.0.0.8 using the servlet-3.1, servlet-4.0, servlet-5.0, or servlet-6.0 feature(s) with the HTTP/2 protocol enabled:
· Upgrade to minimal fix pack levels as required by the interim fix and then apply the Interim Fix that resolves PH66953
--OR--
· Apply Liberty Fix Pack 25.0.0.9 or later (targeted availability 3Q2025).
Additional interim fixes may be available and linked off the interim fix download page.
