Last modified

CVE-2024-21530 is a medium-severity vulnerability rated 4.5/10 on the CVSS scale. 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.. EPSS estimates a 0.14% chance of exploitation in the next 30 days.
