An authorization bypass vulnerability has been identified in EspoCRM versions prior to 10.1.0. The issue resides in the PDF rendering pipeline, specifically within the 'ImageSourceProvider::get' function of the 'application/Espo/Tools/Pdf/Dompdf/ImageSourceProvider.php' file. The vulnerability allows users with edit access to PDF templates to access image attachments from other users or records by manipulating the attachment ID. This bypasses normal access controls and could be exploited remotely.
Users are advised to update to EspoCRM version 10.1.0 or later, where this vulnerability has been patched.
