The short version

What changed, and why it matters

This is a broad security patch for BTCPay Server 2.4.3. It fixes several access-control gaps (for example, lower-privileged store users could manage server admins or see sensitive API keys), hardens user-profile changes by requiring the current password, removes a third-party comment system (Disqus) that could inject scripts, adds rate limits to public invoice creation, stops plugins with known incompatibilities from loading, and tightens validation of Bitcoin transactions and multisig wallet setup. The changelog explicitly calls it a security release and recommends updating for multi-user servers.

Recommended action

Upgrade to BTCPay Server 2.4.3 promptly, especially on shared or multi-user instances. Review store membership and server-admin assignments after upgrading, and verify that any custom plugins are compatible with the new loader blacklist.
