EspoCRM is an open source customer relationship management application used by businesses to manage customer interactions and data.

## How to fix

- Fixed in 9.3.7

## Technical details

The vulnerability exists in the portal Note API access control logic: while stream list responses properly filter out notes with isInternal set to true, the direct single-note fetch endpoint (checkEntityRead) does not enforce the same restriction. An authenticated portal user can bypass the access check by making a direct API request if they know the note identifier, allowing them to read notes intended only for internal agents. The fix adds an explicit isInternal() check in the AclPortal\Note\AccessChecker to deny access to internal notes at read time.
