Prioritising Microsoft Patch Tuesday August 2026

Microsoft Patch Tuesday August 2026 is one of those releases where the order matters more than the headline count. I would patch the exploited flaw first, then the network-facing RCEs, and only then worry about the tidier backlog.

Access control in WrappedADS authorised mint flow

MMR proof indexing in a bridge dispatcher audit

The ugly part of an Ethereum bridge dispatcher is not the proof itself, it is the gap between a tidy verification trace and the bytes that finally reach custody logic. If those two ever diverge, the...
