WebMCP: Threat Modeling Approach
- Issue: webmachinelearning/webmcp#154
- Security and privacy considerations: Security and Privacy Considerations for WebMCP
- What are we working on: Readme file
We should discuss the approach on how to work with them: (a) filing issues, or (b) we should be to reverse-engineer the implicit threat model from the current security and privacy considerations. A possible outcome is an hybrid approach: file a small number of clear security issues if something arises, while recommending a compact threat-modeling note to guide the broader review.

Devices and Sensors WG 2026 Charter review
- Issue: w3c/strategy#530
- Draft charter: [DRAFT] Devices and Sensors Working Group Charter
- Background reading: Peripheral Instinct: How External Devices Breach Browser Sandboxes
The proposed Devices and Sensors WG charter should be reviewed with particular attention to APIs that expose device capabilities or persistent device state. The Peripheral Instinct paper has a useful analysis: low-level web access to peripherals can shift the trust boundary from a trusted host operating system to a potentially malicious web origin, with effects that may survive the browser session and cross the ordinary browser sandbox boundary. Should we require a threat model during chartering to understand if the residual threas are accettable?
