Published Nov 29, 2024CWE-697EPSS 0.83%

Overview

CVE-2024-53861 is a low-severity vulnerability. It was published on November 29, 2024 and has a CVSS 3.1 base score of 2.2 (LOW).

This vulnerability has a CVSS 3.1 base score of 2.2, rated LOW. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
