Severity by source
AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
AC:H because successful exploitation depends on a pre-parsing co-component being deployed on the same path, a condition entirely beyond attacker control.

Per-file size and file-count upload limit enforcement in Apache Wicket 8.x through 10.x can be bypassed when a co-deployed servlet component pre-consumes the multipart request body before Wicket processes it. Affected deployments fall back to HttpServletRequest#getParts(), which silently skips Wicket's configured Form#setFileMaxSize and Form#setFileCountMax constraints, allowing remote unauthenticated submitters to upload files larger or more numerous than the application intends to permit. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Two concurrent conditions must be met: (1) Apache Wicket 8.0.0-8.18.0, 9.0.0-9.23.0, or 10.0.0-10.10.0 must be deployed with at least one of Form#setFileMaxSize or Form#setFileCountMax configured-applications using neither limit are explicitly stated as unaffected; (2) the upload request path must also be served by a component that pre-consumes the multipart body, specifically Spring Boot's multipart resolver, a servlet annotated with @MultipartConfig, or any filter that calls HttpServletRequest#getParameter() on multipart requests. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD-assigned CVSS 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) overstates practical exploitation probability because it does not account for the deployment-specific precondition: the vulnerability is only reachable when a separate servlet or filter pre-parses the multipart body, a configuration beyond attacker control. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade to Apache Wicket 8.19.0, 9.24.0, or 10.11.0, which apply per-file and file-count limits consistently via both the Commons FileUpload and the HttpServletRequest#getParts() code paths. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Determine if Apache Wicket 8.x-10.x is deployed in production and identify any co-deployed servlet components configured to pre-consume multipart request bodies. …
