CVE-2025-48927: TeleMessage TM SGNL contains an initialization of a resource with an insecure default vulnerability. This vulnerability relies on how the Spring Boot Actuator is configured with an exposed heap dump endpoint at a /heapdump URI. CVE-2025-48928: TeleMessage TM SGNL contains an exposure of core dump file to an unauthorized control sphere Vulnerability. This vulnerability is based on a JSP application in which the heap content is roughly equivalent to a "core dump" in which a password previously sent over HTTP would be included in this dump.
