CVE-2025-52913 is an unauthenticated path traversal vulnerability in the NuPoint Unified Messaging component of Mitel MiCollab through version 9.8 SP2 (9.8.2.12). Insufficient validation of user-supplied data used to construct file paths permits directory traversal sequences, including encoded equivalents, to access files and locations outside the intended path. The issue is described as a bypass of CVE-2024-41713.
