The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - PyJWT is a Python implementation of JSON Web Token standards. From 2.4.0 until 2.14.0, PyJWT HMACAlgorithm.preparekey is affected because asymmetric-key guard...

SUSE CVE-2026-102271

PyJWT is a Python implementation of JSON Web Token standards. From 2.4.0 until 2.14.0, PyJWT HMACAlgorithm.preparekey is affected because asymmetric-key guard relies on textual markers that are absent from DER encoding. This occurs when an application mixes HMAC and asymmetric algorithms and...

GHSA-P4G4-X82P-Q773 PyJWT: Public keys in DER form are accepted as HMAC secrets, bypassing the CVE-2022-29217 guard

Summary HMACAlgorithm.preparekey blocks asymmetric keys from being used as HMAC secrets by searching for text markers only. It looks for -----BEGIN and for an ssh- prefix. The same key in DER form is binary ASN.1 and has neither marker, so it passes the check and is used as an HMAC secret. An...

CVE-2026-102271

The PyJWT Python library (versions 2.4.0 through 2.14.0 ) is vulnerable in the HMACAlgorithm.prepare_key function. The root cause is that the asymmetric-key guard relies on textual markers that are missing from DER encoding . When an application mixes HMAC and asymmetric algorithms and provides a...
