SCA: security update for PyJWT (GHSA-75c5-xw7c-p5pm)

low Tenable Self-Hosted Container Security Plugin ID 411834

Description

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

- pyjwt is a JSON Web Token implementation in Python. An incorrect string comparison is run for `iss`
checking, resulting in `"acb"` being accepted for `"_abc_"`. This is a bug introduced in version 2.10.0:
checking the "iss" claim changed from `isinstance(issuer, list)` to `isinstance(issuer, Sequence)`. Since
str is a Sequnce, but not a list, `in` is also used for string comparison. This results in `if "abc" not
in "__abcd__":` being checked instead of `if "abc" != "__abc__":`. Signature checks are still present so
real world impact is likely limited to denial of service scenarios. This issue has been patched in version
2.10.1. All users are advised to upgrade. There are no known workarounds for this vulnerability.
(CVE-2024-53861)
