Subscriber-level restricted actions via unverified AJAX requests
Published Apr 17, 2025 · Updated Apr 28, 2026
Missing authorization in iTRON WP Logger 2.2 and earlier allows remote authenticated users to invoke restricted actions through AJAX. The 2.2.1 changelog attributes the fix to nonce verification for AJAX queries, indicating that affected requests were accepted without that check. Subscriber-level access is required; published records do not identify the affected handler or the action's exact integrity or availability consequence.
