From 03e2a832f14b10eab65c9cf9de458b1f728ee787 Mon Sep 17 00:00:00 2001 From: swantaafuwai-hub Date: Wed, 21 Oct 2026 10:09:26 +0000 Subject: [PATCH] fix(analytics): Add authentication to record_metric functions Fixes critical vulnerability where record_metric and record_metric_at allowed any account to write arbitrary metrics. Implements whitelist-based authorization with admin-controlled reporters. Changes: - Add initialize() function with admin setup - Add add/remove_authorized_reporter() for reporter management - Protect record_metric() with authorization check - Protect record_metric_at() with authorization check and require_auth() - Add is_authorized_reporter() query function - Prevent duplicate metric entries - Add comprehensive auth boundary tests (24 test cases) Security properties: - Only whitelisted reporters can record metrics - Admin-controlled reporter whitelist - Immutable audit trail (metrics cannot be modified) - Duplicate prevention - Soroban require_auth() enforcement Documentation: - ANALYTICS_AUTH_FIX.md: Detailed fix explanation and integration guide - ANALYTICS_FIX_VERIFICATION.md: Complete security verification Impact: HIGH - Closes data integrity vulnerability --- ANALYTICS_AUTH_FIX.md | 202 ++++++++ ANALYTICS_FIX_VERIFICATION.md | 286 ++++++++++++ contracts/analytics/src/lib.rs | 264 ++++++++++- contracts/analytics/tests/auth_boundary.rs | 511 +++++++++++++++++++++ 4 files changed, 1258 insertions(+), 5 deletions(-) create mode 100644 ANALYTICS_AUTH_FIX.md create mode 100644 ANALYTICS_FIX_VERIFICATION.md create mode 100644 contracts/analytics/tests/auth_boundary.rs diff --git a/ANALYTICS_AUTH_FIX.md b/ANALYTICS_AUTH_FIX.md new file mode 100644 index 00000000..ddb2b9d8 --- /dev/null +++ b/ANALYTICS_AUTH_FIX.md @@ -0,0 +1,202 @@ +# Analytics Contract Authentication Vulnerability Fix + +## Issue Summary + +The analytics contract's `record_metric` and `record_metric_at` functions had no authentication requirement.
