Add server.request.body.filenames support for Akka HTTP, Grizzly, and Spring Boot#11173
Conversation
Extract filenames from Multipart.FormData.BodyPart.Strict using getFilename() in handleMultipartStrictFormData() and fire the requestFilesFilenames() IG event. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Enable the filename upload test for: Spring Boot, Grizzly, Play 2.5/2.6, and Akka HTTP test variants (with appropriate false overrides for sync and version-constrained cases). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…eldMultiMap path - Jersey 2.0/3.0 (MultiPartReaderServerSideInstrumentation): extract filenames from FormDataBodyPart.getContentDisposition().getFileName() and fire requestFilesFilenames callback after requestBodyProcessed. Grizzly uses Jersey's multipart reader. - Akka HTTP 10.0 handleStrictFormData: the formFieldMultiMap path goes through StrictFormCompanionInstrumentation → handleStrictFormData, not through handleMultipartStrictFormData. Added filename extraction from Multipart$FormData$BodyPart$Strict.getFilename() and fires requestFilesFilenames callback with blocking support for this path.

What Does This Do
Instruments multipart request handling in Akka HTTP, Grizzly (via Jersey), and Spring Boot to fire the
requestFilesFilenamesAppSec gateway event, enabling WAF rules that act on uploaded file names.Akka HTTP 10.0 / 10.6
Two distinct code paths handle multipart form data:
Unmarshal(...).to[Multipart.FormData.Strict]→handleMultipartStrictFormData: already instrumented in the parent commit; iteratesgetStrictParts()and callspart.getFilename().formFieldMultiMap/formFields→StrictFormCompanionInstrumentation→handleStrictFormData: previously missing. This path receivesMultipart$FormData$BodyPart$Strictobjects via reflection onStrictForm.Field; addedbodyPart.getFilename()extraction and firesrequestFilesFilenameswith full blocking support (AkkaBlockResponseFunction.setUnmarshallBlock(true)).Akka HTTP 10.6 is excluded from local builds (requires
akkaRepositoryToken); tested in CI only.Grizzly 2.x (Jersey 2.0 / 3.0)
Grizzly routes multipart requests through Jersey's
MultiPartReaderServerSide.readMultiPart().MultiPartReaderServerSideInstrumentationalready intercepted that method and firedrequestBodyProcessed, but never extracted filenames. AddedFormDataBodyPart.getContentDisposition().getFileName()extraction for each body part; firesrequestFilesFilenamesafterrequestBodyProcessedwith blocking support.Both
jersey-appsec-2.0(javax.ws.rs) andjersey-appsec-3.0(jakarta.ws.rs) are updated with identical logic.Spring Boot
Spring Boot over Tomcat routes multipart through
ParsePartsInstrumentation, which was already instrumented for filenames in a prior commit. Only thetestBodyFilenames()test flag was needed.akka-http-10.0(Unmarshal path)akka-http-10.0(formFieldMultiMap path)handleStrictFormDatanow firesrequestFilesFilenamesakka-http-10.6jersey-appsec-2.0jersey-appsec-3.0spring-webmvc-3.1testBodyFilenames() { true }grizzly-http-2.3.20testBodyFilenames() { true }Motivation
Part of APPSEC-61873 —
server.request.body.filenamesimplementation across server frameworks.Additional Notes
Depends on the Akka HTTP parent commit already merged on this branch.
