Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability was detected in CherryHQ cherry-studio up to 1.9.7. This affects the function sha256 of the file src/main/services/memory/MemoryService.ts of the component CherryIN Preload API. Performing a manipulation of the argument state results in authorization bypass. The attack can be initiated remotely. The attack's complexity is rated as high. It is indicated that the exploitability is difficult. The exploit is now public and may be used. The vendor explains, that "[m]emory is planned to be removed in v2 version."

dbcve analysis
How this class of weakness works · CWE-285

The application confirms who you are but does not properly check whether you are permitted to perform a given action, so authenticated users reach functions or data meant for others. Attackers test roles and object references to find the gap. Remediation is an authorization check on every request, evaluated against the acting user's actual permissions.

Recommended fix Moderate confidence

Version 2.x (when available) - vendor stated memory will be removed in v2

  1. 1. Check the current installed version of Cherry Studio (go to Help > About or similar)
  2. 2. Visit the official Cherry Studio releases page at https://github.com/CherryHQ/cherry-studio/releases to identify the latest stable version
  3. 3. If version 2.x is available, upgrade to it as the vendor has stated memory functionality will be removed in v2
  4. 4. If v2 is not yet available, monitor the PR at https://github.com/CherryHQ/cherry-studio/pull/15413 for merge status and subsequent release
  5. 5. After upgrading, verify the sha256 function in src/main/services/memory/MemoryService.ts no longer processes state arguments unsafely
Caveat If migrating to v2, review any configuration or data migration requirements as memory features are being removed entirely
