CVSS 4.9 · Medium EPSS 0,21%

Kerentanan Inefficient Regular Expression Complexity pada pyjwt project pyjwt. Skor CVSS 3.1 4.9 (Medium) menurut NVD.

Deskripsi (NVD)

PyJWT is a Python implementation of JSON Web Token standards. Prior to 2.14.0, PyJWT is_pem_format is affected because lazy PEM regular expression backtracks extensively. This occurs when a certificate-like input contains repeated BEGIN markers without a matching END marker. As a result, is_pem_format performs unbounded backtracking while searching for a PEM end marker. Consequently, an attacker can cause intensive CPU consumption. This issue is fixed in version 2.14.0.
