Note: public master fix commit 2d6b77049f1c on 2026-03-10. the official dcrd release-v2.1.4 notes, published on 2026-04-07, include the limited-user authentication fix via PR #3660: https://github.com/decred/dcrd/releases/tag/release-v2.1.4. this corrects the previously recorded v1.10.6 version; v2.1.4 is a verified release containing the fix, not a claim about the earliest fixed version on every branch. the change prevents limited-only access from gaining administrator privileges when admin auth is unset.
