CVSS 3.1
4.5 mediumCVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:NCVE-2024-21530
Medium (4.5). EPSS 0.1% chance of exploitation in the next 30 days. Fixed in cocoon 0.4.0.
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.
