arXiv:2611.13965v1 Announce Type: new Abstract: MiniApps are increasingly central to super-app ecosystems, yet architectural differences complicate the transfer of security analysis techniques across platforms. Existing WeChat analyzers rely on packaged applications and platform-specific APIs, limiting their direct applicability to Telegram's web-based MiniApps. We present a qualitative comparison of WeChat Mini Programs and Telegram MiniApps, grounded in official documentation, prior research, and manual analysis of a specific Telegram Android source revision. Using a shared taxonomy of security controls, assets, and threat sources, we examine execution environments, communication paths, and trust boundaries. WeChat provides a dedicated MiniApp runtime; Telegram combines web execution with host controls. Both retain developer responsibilities for backend authentication and resource authorization. Two worked examples derive requirements for cross-platform analysis: distinguishing credential roles and validation boundaries, and associating host capabilities with concrete execution contexts and permission handlers. These findings inform future automated analysis without ranking the ecosystems by security or claiming validated vulnerability detection.
