CVE-2026-85093Public exploitNetwork attack vectorHinoki check available

Cross-user message disclosure via unfiltered pagination

Published Sep 3, 2026 · Updated Sep 3, 2026

Incorrect authorization in Cheshire Cat AI core 1.8.0 through 1.9.2 allows remote authenticated users to read other users' messages. The memory points route calls get_all_points with the requested limit and offset but supplies no source filter tied to the caller. MEMORY:READ permission and a valid account are required; pagination exposes stored conversation text and associated personal data across the instance.
