Apps Accepting User Links Have No Standard Malicious URL Defense
Any application accepting user-provided links faces open redirect, SSRF, and phishing risks, but there is no consensus pattern for validating and sandboxing URLs at the application layer. Developers implement ad hoc solutions ranging from naive blocklists to nothing at all.

Google Play Data Safety Labels Are Self-Reported and Not Independently Verified
Google Play's Data Safety section relies entirely on developer self-declaration with no automated verification against actual app behavior. Users and IT teams cannot trust these labels when making privacy decisions. The gap between declared and actual data collection practices is verifiable through network analysis, but no mainstream tool surfaces this clearly.

LLM applications processing Japanese text face unique prompt injection vectors that standard defenses may not catch. Developers building Japanese-language LLM apps lack established patterns for handling language-specific injection attacks.
No sanitization layer between MCP tool output and AI model context
AI agents using MCP-connected tools pass raw external data—scraped web content, API responses—directly into model context with no boundary between system instructions and untrusted tool output. This creates a prompt injection surface that is currently unaddressed by any mature tooling. Teams building agentic systems have no standard way to filter, monitor, or sandbox tool response traffic before it reaches the model.
