Hi,
The following vulnerability was published for pyjwt.
CVE-2022-29217[0]:
| PyJWT is a Python implementation of RFC 7519. PyJWT supports multiple
| different JWT signing algorithms. With JWT, an attacker submitting the
| JWT token can choose the used signing algorithm. The PyJWT library
| requires that the application chooses what algorithms are supported.
| The application can specify `jwt.algorithms.get_default_algorithms()`
| to get support for all algorithms, or specify a single algorithm. The
| issue is not that big as
| `algorithms=jwt.algorithms.get_default_algorithms()` has to be used.
| Users should upgrade to v2.4.0 to receive a patch for this issue. As a
| workaround, always be explicit with the algorithms that are accepted
| and expected when decoding.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
