Name of the Vulnerable Software and Affected Versions TeleMessage archiving backend versions through 2025-05-05

Description The issue concerns the acceptance of API calls from the TM SGNL (aka Archive Signal) app to request an authentication token, using hardcoded credentials. The credentials used are logfile for the user and enRR8UVVywXYbFkqU#QDPRkO for the password.
