Linux Distros Unpatched Vulnerability : CVE-2026-102268

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. Prior to 2.14.0, ispemformat in jwt/utils.py is affected because ispemformat does not recognize...

PyJWT: PyJWK accepts empty HMAC keys, bypassing PyJWT's empty-key validation

Summary A service that verifies HS256 tokens using an empty oct JWK through PyJWK, including a PyJWK obtained from PyJWKSet, can therefore accept attacker-generated tokens as authenticated. PyJWT 2.13.0 rejects an empty HMAC key when it is supplied through the raw str/bytes key path, but accepts...

GHSA-9J54-FG26-WV3R PyJWT: PyJWK accepts empty HMAC keys, bypassing PyJWT's empty-key validation

Summary A service that verifies HS256 tokens using an empty oct JWK through PyJWK, including a PyJWK obtained from PyJWKSet, can therefore accept attacker-generated tokens as authenticated. PyJWT 2.13.0 rejects an empty HMAC key when it is supplied through the raw str/bytes key path, but accepts...

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...

Improper Verification of Cryptographic Signature

Overview PyJWT is a Python implementation of RFC 7519. Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature via the verifysignature method in jwt/apijws.py when a PyJWK object is used to verify an HMAC-signed token. In the vulnerable code path,...

Improper Verification of Cryptographic Signature

Overview PyJWT is a Python implementation of RFC 7519. Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature via ispemformat in jwt/utils.py, which fails to recognize certain loader-accepted PEM formatting variants as valid PEM. The fix for...

Improper Verification of Cryptographic Signature

Overview PyJWT is a Python implementation of RFC 7519. Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature via the preparekey method in jwt/algorithms.py, where DER-encoded public keys are accepted as HMAC secrets without rejection. An attacker who...

CVE-2026-102273

A flaw was found in PyJWT. This vulnerability allows an unauthenticated remote attacker to bypass authentication by forging arbitrary JSON Web Tokens JWTs. When an application allows both symmetric and asymmetric algorithms, PyJWT fails to properly validate public JSON Web Key JWK container...

CVE-2026-102271

A flaw was found in PyJWT. The library fails to identify asymmetric public keys supplied in Distinguished Encoding Rules DER format, inadvertently treating the public data as a shared secret in Hash-based Message Authentication Code HMAC operations. If an application supports both asymmetric and...

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...
