In `@cla-backend-go/swagger/common/prepare-sign-input.yaml`:
- Around line 16-21: Restrict the returnUrl schema and preparation flow to HTTPS
URLs with hosts from the configured Contributor Console Approved List. Update
the validation around returnUrl and ensure getActiveSignatureReturnURL only
returns values that pass this approved-host check; reject all other schemes or
origins.
In `@cla-backend-go/v2/self_serve_sign/service.go`:
- Around line 187-210: Update the acceptVerifiedGithubID flow and its
githubUserDetails/GetUserDetails call chain to propagate the request context
instead of context.TODO(), and configure the OAuth client with a bounded HTTP
timeout. Preserve the existing GitHub identity validation and error handling
behavior.
- Around line 308-330: Update enrichUser so GitHubID and GitlabID values in the
updates map remain numeric int64 values instead of strconv.FormatInt strings
before calling UpdateUser. Preserve the existing field names and username
handling, ensuring DynamoDB marshals both ID attributes as numbers.
In `@cla-backend-go/v2/sign/handlers.go`:
- Around line 287-304: Replace the package-level iclaGitHubPayload usage with
request-scoped context storage in DocusignMiddleware. Update all four ICLA
callback handlers, including IclaCallbackSelfServeHandler, to retrieve the
payload from each request’s context before invoking the corresponding service
method, preserving per-request isolation under concurrent callbacks.
In `@cla-backend-go/v2/sign/service.go`:
- Around line 1113-1118: Update SignedIndividualCallbackSelfServe to remove the
active_signature metadata for userID only after the delegated callback confirms
a Completed DocuSign status; preserve the metadata for non-terminal callbacks
and propagate existing callback errors.
- Around line 1715-1718: Update getIndividualSignatureCallbackURLGitlab to
detect self-serve metadata with utils.IsSelfServeActiveSignature before
validating repository_id and merge_request_id, returning the existing self-serve
callback URL immediately. Add a GitLab self-serve test covering metadata without
those fields and verifying the callback URL.
In `@utils/prepare_sign.sh`:
- Line 137: Update the DEBUG curl trace in the prepare-sign flow to replace
${auth[0]} with a fixed redacted header value, while preserving the rest of the
diagnostic command output and request behavior.
- Around line 58-64: Update the target-selection flow in prepare_sign.sh to
require an explicit confirmation variable before any POST that can create
records when the resolved target is non-local, including custom API_URL values;
display the resolved endpoint and abort unless confirmation is explicitly
enabled. Preserve local-target behavior and the existing unknown-STAGE
validation.
Apply the same fix in `@utils/prepare_sign.sh` around lines 77 - 79: Covered by
the same explicit confirmation requirement before sending mutation requests.

cla-backend-go/cmd/server.go:530
- This exposes a state-changing webhook through middleware that only copies/logs the body; it does not verify a DocuSign Connect HMAC, and the Swagger operation explicitly disables normal authentication. A forged callback can therefore drive signature updates. Validate the
X-DocuSign-Signature-*header against a configured Connect secret before dispatching this handler (and reject missing/invalid signatures).
v2API.AddMiddlewareFor("POST", "/signed/self-serve/individual/{user_id}", sign.DocusignMiddleware)
cla-backend-go/v2/sign/handlers.go:298
- This handler reads a package-global payload that
DocusignMiddlewareoverwrites for every request. Concurrent webhook requests can race and process another request's XML, updating the wrong signature. Keep the payload request-scoped (for example in the request context) and pass that value to the service.
err := service.SignedIndividualCallbackSelfServe(ctx, iclaGitHubPayload, params.UserID)
cla-backend-go/v2/sign/service.go:1139
- This unconditional delete is not correlated with the envelope/signature that was just processed. If DocuSign retries an older completion after the user starts another signing session, the retry deletes the newer
active_signature:<user>record. Store a session/signature or envelope identifier in the metadata and conditionally delete only the matching session.
if err := s.storeRepository.DeleteActiveSignatureMetaData(ctx, fmt.Sprintf("active_signature:%s", userID)); err != nil {
cla-backend-go/v2/self_serve_sign/service.go:279
- All lookup branches in
resolveUsertreat repository errors as ordinary misses. A transient DynamoDB failure can therefore fall through toCreateUser, producing a duplicate record instead of failing the request. Return(user, error)from this helper and propagate lookup errors; only continue when the lookup successfully returns no user.

cla-backend-go/v2/self_serve_sign/service.go:499
- The API permits
githubUsernameorgitlabUsernamewithout a numeric ID, but such an authorized request reaches this fallback and records the LF username as the ACL. The resulting signature is not associated with the provider identity the caller selected. Resolve and verify the provider's numeric ID before recording the session, or reject username-only provider requests.

- Setting only

cla-backend-go/v2/self_serve_sign/service.go:328
- A request that explicitly selects an email can resolve the wrong EasyCLA user.
AuthorizeIdentityalways adds the caller's LF username, and this LF/Gerrit loop runs before the email lookup below, so any existing LF-linked record wins even when the requested email belongs to a different record. The session and response then represent the LF record rather than the selected identity. Prioritize the explicitly requested identity and use the implicit LF username only when no identity was supplied (or LF username was explicitly selected).
for _, lfUsername := range append([]string{allowed.LfUsername}, allowed.GerritUsernames...) {
cla-backend-go/v2/sign/service.go:1132
- The callback path's
userIDis not bound to the envelope before this delegation.SignedIndividualCallbackGerritonly logs that argument and resolves the actual signer fromClientUserId; afterward this method deletesactive_signature:<userID>. A callback payload for one signer posted to another user's path therefore processes the former signature and deletes the latter user's session. Resolve the payload's signature first and require itsSignatureReferenceIDto equaluserIDbefore processing or deleting metadata.
if err := s.SignedIndividualCallbackGerrit(ctx, payload, userID); err != nil {
return err
cla-backend-go/v2/sign/handlers.go:298
- This reads the callback body from the package-global
iclaGitHubPayload.DocusignMiddlewareoverwrites that slice for every request, so concurrent callbacks in the standalone HTTP server can cross-contaminate: one user's handler may process another request's envelope (and the self-serve cleanup can then delete the wrong session). Carry the raw body in the request context or another request-scoped value instead of shared mutable state.
err := service.SignedIndividualCallbackSelfServe(ctx, iclaGitHubPayload, params.UserID)
cla-backend-go/v2/sign/service.go:2979
- The self-serve return URL retrieved here is never applied to the signature. In
RequestIndividualSignature, the returned local is only checked for emptiness; new signatures still useinput.ReturnURLat line 1599, and the existing-signature branch uses it at line 1522 before this fallback runs. Thus a console request that omitsreturn_url(as the active-session fallback permits) stores an empty return target and/v2/return-url/{signature_id}cannot redirect back to Self Serve. Assign the resolved URL to the signature in both creation and regeneration paths.
if utils.IsSelfServeActiveSignature(metadata) {
if selfServeReturnURL, ok := metadata["return_url"].(string); ok {
returnURL = selfServeReturnURL
}
return returnURL, nil

- This new unauthenticated callback is not actually protected by DocuSign HMAC.
sign.DocusignMiddlewareonly copies the body (v2/sign/handlers.go:39-56) and the Swagger operation explicitly hassecurity: [], so any caller can submit XML containing a known signature ID; callback processing marks that signature signed before later document retrieval can fail. Validate the DocuSign signature header against the raw body and reject invalid or missing signatures before invoking the handler.
v2API.AddMiddlewareFor("POST", "/signed/self-serve/individual/{user_id}", sign.DocusignMiddleware)
cla-backend-go/v2/sign/handlers.go:298
- The payload passed here is package-global state written by
DocusignMiddleware. Concurrent GitHub, GitLab, Gerrit, or self-serve callbacks can overwriteiclaGitHubPayloadbetween middleware execution and this handler, causing this user to process another request's envelope and potentially delete the wrong active session. Keep the raw payload on the request/context instead of sharing it across requests.
err := service.SignedIndividualCallbackSelfServe(ctx, iclaGitHubPayload, params.UserID)
cla-backend-go/v2/self_serve_sign/service.go:177
- The API permits signing with only
githubUsernameorgitlabUsername, butidentityACL(allowed)has no username cases and therefore falls through to the caller's LF username. Because self-serve signing later gives this stored ACL precedence, the resulting signature is not recorded under the provider identity the caller selected. Derive the provider ACL from the resolved user's numeric provider ID, or reject provider-username-only requests if a numeric ID cannot be established.
if err := s.recordSigningSession(ctx, userModel.UserID, claGroupID, returnURL, identityACL(allowed)); err != nil {
cla-backend-go/v2/self_serve_sign/service.go:269
- User resolution and creation are not atomic. Two concurrent prepare requests can both observe no matching record and call
CreateUser; the repository writes each under a fresh UUID without a conditional uniqueness check, leaving duplicate EasyCLA users for the same verified identity and nondeterministic GSI lookups. Make creation idempotent with a conditional/transactional identity claim or re-resolve under a per-identity lock.
created, err := s.usersService.CreateUser(newUser, &user.CLAUser{LFUsername: currentUsername})
