Normalized restatement

Certain WSO2 products allow unrestricted file upload with resultant remote code execution. The attacker must use a /fileupload endpoint with a Content-Disposition directory traversal sequence to reach a directory under the web root, such as a ../../../../repository/deployment/server/webapps directory. This affects WSO2 API Manager 2.2.0 up to 4.0.0, WSO2 Identity Server 5.2.0 up to 5.11.0, WSO2 Identity Server Analytics 5.4.0, 5.4.1, 5.5.0 and 5.6.0, WSO2 Identity Server as Key Manager 5.3.0 up to 5.11.0, WSO2 Enterprise Integrator 6.2.0 up to 6.6.0, WSO2 Open Banking AM 1.4.0 up to 2.0.0 and WSO2 Open Banking KM 1.4.0, up to 2.0.0.

Evidence boundaries

  • KEV membership is authoritative for the catalog, not proof of exposure in any environment.
  • EPSS is a dated model probability and not an individual-environment prediction.
  • Affected or fixed status applies only to the exact cited product and version scope; remaining scope stays source-scoped.
  • NVD-carried upstream facts remain derivative; independent corroboration requires a separately authored source.
  • Only NVD metrics validated under the generation-bound calculator are Public Priority eligible; direct CVE record metrics remain display-only.
  • NVD CVSS source eligibility is closed: NVD-authored, exact record-source, or registered same-CVE container origin; unmapped sources remain display-only.
  • Core replay supports the active and immediately prior generation; retrospective valid-at replay is deferred.
  • OSV aggregation and OSV-converted NVD material are not independent corroboration.
  • Red Hat facts are vendor assertions for the exact supplied products.
  • Nonmembership and not-yet-observed states are not proof of safety.
