Vulnerability from fkie_nvd - Published: 2024-10-02 05:15 - Updated: 2026-06-17 07:09
Severity
4.5 (Medium) - CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:N
Summary
Versions of the package cocoon before 0.4.0 are vulnerable to Reusing a Nonce, Key Pair in Encryption when the encrypt, wrap, and dump functions are sequentially called. An attacker can generate the same ciphertext by creating a new encrypted message with the same cocoon object. **Note:** The issue does NOT affect objects created with Cocoon::new which utilizes ThreadRng.
