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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - 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

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2023-076 advisory.

    A vulnerability was found in python-jwt. This issue happens when PyJWT supports multiple different JWT     signing algorithms. This flaw allows an attacker submitting the JWT token to choose the used signing     algorithm, leading to key confusion through non-blocklisted public key formats. (CVE-2022-29217)
