How the CVE Works

CVE-2025-25940 exploits insecure XML deserialization in VisiCut 2.1 through the `loadPlfFile` method in VisiCutModel.java. Attackers craft malicious PLF files containing serialized XML payloads. When processed, the deserialization mechanism executes arbitrary code due to insufficient validation. This occurs because the application trusts untrusted input during object reconstruction, leading to remote code execution (RCE) under the context of the application.
