Hoppscotch Mass Assignment Vulnerability Fix Analysis

Fix Security Vulnerability: Prevent Mass Assignment During Onboarding Vulnerability Overview Vulnerability Type: Mass Assignment Impact: Attackers can set sensitive keys, such as , , and , thereby bypassing authentication or access control. Remediation Measures: - Enable whitelist functionality on the global to strip and reject undeclared fields. - Add a scoped in to explicitly reject unknown fields. - Introduce an whitelist in , allowing only OAuth and SMTP keys. - Replace silent defaults in with explicit rejection of sensitive keys. - Add unit tests in to verify the rejection behavior of sensitive keys. Scope of Impact Unauthenticated Onboarding Configuration Endpoint: Sensitive Keys: , , Remediation Plan Global : Enable whitelist functionality to strip and reject undeclared fields. Scoped : Explicitly reject unknown fields in . Whitelist: Introduce in , allowing only OAuth and SMTP keys. Explicit Rejection: Explicitly reject sensitive keys in . Unit Tests: Add unit tests in to verify the rejection behavior of sensitive keys. Important File Changes : Enable whitelist functionality for the global . : Add a scoped to explicitly reject unknown fields. : Introduce whitelist and explicitly reject sensitive keys. : Add unit tests to verify the rejection behavior of sensitive keys. Flowchart Primary Mitigation: Global strips and rejects undeclared fields. Service Layer Whitelist: in is used for key filtering. Error: The PR description states that , , and are now explicitly rejected, but the actual code still reaches the default branch. Confidence Score Score: 3/5 Explanation: The global change is correct and provides actual protection, but two claimed defense-in-depth layers are non-functional. The service layer whitelist uses on an instantiated class in , returning an empty array. still hits the default for sensitive keys. The unit test masks the error. Overview of Key File Changes : Service layer whitelist is broken; on an uninitialized class returns . : Global correctly enables whitelist functionality. : Removal of from causes type validation regression. : The guard fails when is undefined, causing to reject omitted fields. : New merges / parameters; uses only , missing . : New whitelist test uses plain object literals instead of class instances, masking the error. : Addition of and with correct / on ; existing arg classes receive / validation.
