Description OSIDB Bzimport 2026-02-26 14:27:15 UTC 
A vulnerability was identified in Undertow (as used in Wildfly) where the server prematurely parses and stores multipart/form-data content to the disk when receiving an HTTP GET request, provided the underlying application (e.g., JSF) invokes parameter-parsing methods like getParameterMap().
