CVE-2025-0556 affects Progress Telerik Report Server versions prior to 2025 Q1 (11.0.25.211) when utilizing the older .NET Framework, where non-sensitive inter-process communication occurs over an unencrypted channel. This medium-severity vulnerability (CVSS 6.5) allows for local network traffic sniffing, potentially exposing non-sensitive information due to the lack of encryption (CWE-319).
