CVE-2025-63675Public exploit

Code execution via decrypted pickle deserialization

Published Oct 31, 2025 · Updated Oct 31, 2025

Unsafe deserialization in aes_decrypt_message in NetInvent cryptidy 1.2.4 and earlier allows attackers to execute code via encrypted data. The function decrypts ciphertext and passes the resulting bytes directly to pickle.loads without restricting the reconstructed classes or callable operations. Exploitation requires crafted ciphertext that passes AES authentication and reaches the decryption API; code runs with the calling process's privileges.
