CVE-2026-31252: CosyVoice thru commit 6e01309e01bc93bbeb83bdd996b1182a81aaf11e (2025-30-21) contains an insecure deserialization vulnera

CosyVoice, a text-to-speech framework, has an insecure deserialization vulnerability (CWE-502, a weakness where untrusted data is converted back into executable objects) in how it loads model files. The vulnerability exists because the code uses torch.load() without the weights_only=True security setting, allowing attackers to execute arbitrary code (malicious instructions) on a victim's computer by tricking them into loading a specially crafted model file through the CosyVoice Web UI.
