Exact-text disclosure via globally scoped memory hashes
Published Jun 29, 2026 · Updated Jun 29, 2026
Improper authorization in Cherry Studio 1.9.0 through 1.9.7 allows local users to infer stored memory text and block scoped inserts. The MemoryService.add() path hashes only trimmed memory text, while the hash column is globally unique, so deduplication ignores the user_id and agent_id boundaries enforced by search and list operations. Reachability depends on shared profiles, shared data directories, or untrusted renderer, plugin, or MCP code; the oracle reveals only whether an exact guessed string exists, not the stored memory itself.
