Overview

AI description

Automated description summarized from trusted sources.

CVE-2025-47729 is a vulnerability found in the TeleMessage TM SGNL application. The archiving backend of TeleMessage stores cleartext copies of messages from TM SGNL app users. This differs from the vendor's documentation, which describes "End-to-End encryption from the mobile phone through to the corporate archive". This vulnerability was exploited in the wild in May 2025. The vulnerability means that unauthorized individuals with high-privilege access could potentially view sensitive message contents in plaintext. This could compromise user privacy and corporate communication confidentiality because the messages were expected to be securely encrypted.

Description: The TeleMessage archiving backend through 2025-05-05 holds cleartext copies of messages from TM SGNL (aka Archive Signal) app users, which is different functionality than described in the TeleMessage "End-to-End encryption from the mobile phone through to the corporate archive" documentation, as exploited in the wild in May 2025.
