| Doc Text: |
A flaw was found in pyjwt. The library uses weak encryption, allowing an attacker to potentially decrypt sensitive data. A network-based attacker can exploit this vulnerability without authentication, possibly resulting in a denial of service or data exposure. This weakness stems from the use of inadequate cryptographic algorithms.
